+
+As such, it allows licensees and sublicensees of Sun's GPL2 OpenJDK Code to

+The GNU General Public License (GPL)
+
+Version 2, June 1991
+
+Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
+
+Everyone is permitted to copy and distribute verbatim copies of this license
+document, but changing it is not allowed.
+
+Preamble
+
+The licenses for most software are designed to take away your freedom to share
+and change it. By contrast, the GNU General Public License is intended to
+guarantee your freedom to share and change free software--to make sure the
+software is free for all its users. This General Public License applies to
+most of the Free Software Foundation's software and to any other program whose
+authors commit to using it. (Some other Free Software Foundation software is
+covered by the GNU Library General Public License instead.) You can apply it to
+your programs, too.
+
+When we speak of free software, we are referring to freedom, not price. Our
+General Public Licenses are designed to make sure that you have the freedom to
+distribute copies of free software (and charge for this service if you wish),
+that you receive source code or can get it if you want it, that you can change
+the software or use pieces of it in new free programs; and that you know you
+can do these things.
+
+To protect your rights, we need to make restrictions that forbid anyone to deny
+you these rights or to ask you to surrender the rights. These restrictions
+translate to certain responsibilities for you if you distribute copies of the
+software, or if you modify it.
+
+For example, if you distribute copies of such a program, whether gratis or for
+a fee, you must give the recipients all the rights that you have. You must
+make sure that they, too, receive or can get the source code. And you must
+show them these terms so they know their rights.
+
+We protect your rights with two steps: (1) copyright the software, and (2)
+offer you this license which gives you legal permission to copy, distribute
+and/or modify the software.
+
+Also, for each author's protection and ours, we want to make certain that
+everyone understands that there is no warranty for this free software. If the
+software is modified by someone else and passed on, we want its recipients to
+know that what they have is not the original, so that any problems introduced
+by others will not reflect on the original authors' reputations.
+
+Finally, any free program is threatened constantly by software patents. We
+wish to avoid the danger that redistributors of a free program will
+individually obtain patent licenses, in effect making the program proprietary.
+To prevent this, we have made it clear that any patent must be licensed for
+everyone's free use or not licensed at all.
+
+The precise terms and conditions for copying, distribution and modification
+follow.
+
+TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+0. This License applies to any program or other work which contains a notice
+placed by the copyright holder saying it may be distributed under the terms of
+this General Public License. The "Program", below, refers to any such program
+or work, and a "work based on the Program" means either the Program or any
+derivative work under copyright law: that is to say, a work containing the
+Program or a portion of it, either verbatim or with modifications and/or
+translated into another language. (Hereinafter, translation is included
+without limitation in the term "modification".) Each licensee is addressed as
+"you".
+
+Activities other than copying, distribution and modification are not covered by
+this License; they are outside its scope. The act of running the Program is
+not restricted, and the output from the Program is covered only if its contents
+constitute a work based on the Program (independent of having been made by
+running the Program). Whether that is true depends on what the Program does.
+
+1. You may copy and distribute verbatim copies of the Program's source code as
+you receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice and
+disclaimer of warranty; keep intact all the notices that refer to this License
+and to the absence of any warranty; and give any other recipients of the
+Program a copy of this License along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and you may
+at your option offer warranty protection in exchange for a fee.
+
+2. You may modify your copy or copies of the Program or any portion of it, thus
+forming a work based on the Program, and copy and distribute such modifications
+or work under the terms of Section 1 above, provided that you also meet all of
+these conditions:
+
+ a) You must cause the modified files to carry prominent notices stating
+ that you changed the files and the date of any change.
+
+ b) You must cause any work that you distribute or publish, that in whole or
+ in part contains or is derived from the Program or any part thereof, to be
+ licensed as a whole at no charge to all third parties under the terms of
+ this License.
+
+ c) If the modified program normally reads commands interactively when run,
+ you must cause it, when started running for such interactive use in the
+ most ordinary way, to print or display an announcement including an
+ appropriate copyright notice and a notice that there is no warranty (or
+ else, saying that you provide a warranty) and that users may redistribute
+ the program under these conditions, and telling the user how to view a copy
+ of this License. (Exception: if the Program itself is interactive but does
+ not normally print such an announcement, your work based on the Program is
+ not required to print an announcement.)
+
+These requirements apply to the modified work as a whole. If identifiable
+sections of that work are not derived from the Program, and can be reasonably
+considered independent and separate works in themselves, then this License, and
+its terms, do not apply to those sections when you distribute them as separate
+works. But when you distribute the same sections as part of a whole which is a
+work based on the Program, the distribution of the whole must be on the terms
+of this License, whose permissions for other licensees extend to the entire
+whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest your
+rights to work written entirely by you; rather, the intent is to exercise the
+right to control the distribution of derivative or collective works based on
+the Program.
+
+In addition, mere aggregation of another work not based on the Program with the
+Program (or with a work based on the Program) on a volume of a storage or
+distribution medium does not bring the other work under the scope of this
+License.
+
+3. You may copy and distribute the Program (or a work based on it, under
+Section 2) in object code or executable form under the terms of Sections 1 and
+2 above provided that you also do one of the following:
+
+ a) Accompany it with the complete corresponding machine-readable source
+ code, which must be distributed under the terms of Sections 1 and 2 above
+ on a medium customarily used for software interchange; or,
+
+ b) Accompany it with a written offer, valid for at least three years, to
+ give any third party, for a charge no more than your cost of physically
+ performing source distribution, a complete machine-readable copy of the
+ corresponding source code, to be distributed under the terms of Sections 1
+ and 2 above on a medium customarily used for software interchange; or,
+
+ c) Accompany it with the information you received as to the offer to
+ distribute corresponding source code. (This alternative is allowed only
+ for noncommercial distribution and only if you received the program in
+ object code or executable form with such an offer, in accord with
+ Subsection b above.)
+
+The source code for a work means the preferred form of the work for making
+modifications to it. For an executable work, complete source code means all
+the source code for all modules it contains, plus any associated interface
+definition files, plus the scripts used to control compilation and installation
+of the executable. However, as a special exception, the source code
+distributed need not include anything that is normally distributed (in either
+source or binary form) with the major components (compiler, kernel, and so on)
+of the operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering access to copy
+from a designated place, then offering equivalent access to copy the source
+code from the same place counts as distribution of the source code, even though
+third parties are not compelled to copy the source along with the object code.
+
+4. You may not copy, modify, sublicense, or distribute the Program except as
+expressly provided under this License. Any attempt otherwise to copy, modify,
+sublicense or distribute the Program is void, and will automatically terminate
+your rights under this License. However, parties who have received copies, or
+rights, from you under this License will not have their licenses terminated so
+long as such parties remain in full compliance.
+
+5. You are not required to accept this License, since you have not signed it.
+However, nothing else grants you permission to modify or distribute the Program
+or its derivative works. These actions are prohibited by law if you do not
+accept this License. Therefore, by modifying or distributing the Program (or
+any work based on the Program), you indicate your acceptance of this License to
+do so, and all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+6. Each time you redistribute the Program (or any work based on the Program),
+the recipient automatically receives a license from the original licensor to
+copy, distribute or modify the Program subject to these terms and conditions.
+You may not impose any further restrictions on the recipients' exercise of the
+rights granted herein. You are not responsible for enforcing compliance by
+third parties to this License.
+
+7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues), conditions
+are imposed on you (whether by court order, agreement or otherwise) that
+contradict the conditions of this License, they do not excuse you from the
+conditions of this License. If you cannot distribute so as to satisfy
+simultaneously your obligations under this License and any other pertinent
+obligations, then as a consequence you may not distribute the Program at all.
+For example, if a patent license would not permit royalty-free redistribution
+of the Program by all those who receive copies directly or indirectly through
+you, then the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under any
+particular circumstance, the balance of the section is intended to apply and
+the section as a whole is intended to apply in other circumstances.
+
+It is not the purpose of this section to induce you to infringe any patents or
+other property right claims or to contest validity of any such claims; this
+section has the sole purpose of protecting the integrity of the free software
+distribution system, which is implemented by public license practices. Many
+people have made generous contributions to the wide range of software
+distributed through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing to
+distribute software through any other system and a licensee cannot impose that
+choice.
+
+This section is intended to make thoroughly clear what is believed to be a
+consequence of the rest of this License.
+
+8. If the distribution and/or use of the Program is restricted in certain
+countries either by patents or by copyrighted interfaces, the original
+copyright holder who places the Program under this License may add an explicit
+geographical distribution limitation excluding those countries, so that
+distribution is permitted only in or among countries not thus excluded. In
+such case, this License incorporates the limitation as if written in the body
+of this License.
+
+9. The Free Software Foundation may publish revised and/or new versions of the
+General Public License from time to time. Such new versions will be similar in
+spirit to the present version, but may differ in detail to address new problems
+or concerns.
+
+Each version is given a distinguishing version number. If the Program
+specifies a version number of this License which applies to it and "any later
+version", you have the option of following the terms and conditions either of
+that version or of any later version published by the Free Software Foundation.
+If the Program does not specify a version number of this License, you may
+choose any version ever published by the Free Software Foundation.
+
+10. If you wish to incorporate parts of the Program into other free programs
+whose distribution conditions are different, write to the author to ask for
+permission. For software which is copyrighted by the Free Software Foundation,
+write to the Free Software Foundation; we sometimes make exceptions for this.
+Our decision will be guided by the two goals of preserving the free status of
+all derivatives of our free software and of promoting the sharing and reuse of
+software generally.
+
+NO WARRANTY
+
+11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR
+THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE
+STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE
+PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED,
+INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND
+FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND
+PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE,
+YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL
+ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE
+PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR
+INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA
+BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
+FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER
+OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
+
+END OF TERMS AND CONDITIONS
+
+How to Apply These Terms to Your New Programs
+
+If you develop a new program, and you want it to be of the greatest possible
+use to the public, the best way to achieve this is to make it free software
+which everyone can redistribute and change under these terms.
+
+To do so, attach the following notices to the program. It is safest to attach
+them to the start of each source file to most effectively convey the exclusion
+of warranty; and each file should have at least the "copyright" line and a
+pointer to where the full notice is found.
+
+ One line to give the program's name and a brief idea of what it does.
+
+ Copyright (C) <year> <name of author>
+
+ This program is free software; you can redistribute it and/or modify it
+ under the terms of the GNU General Public License as published by the Free
+ Software Foundation; either version 2 of the License, or (at your option)
+ any later version.
+
+ This program is distributed in the hope that it will be useful, but WITHOUT
+ ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or
+ FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for
+ more details.
+
+ You should have received a copy of the GNU General Public License along
+ with this program; if not, write to the Free Software Foundation, Inc., 59
+ Temple Place, Suite 330, Boston, MA 02111-1307 USA
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this when it
+starts in an interactive mode:
+
+ Gnomovision version 69, Copyright (C) year name of author Gnomovision comes
+ with ABSOLUTELY NO WARRANTY; for details type 'show w'. This is free
+ software, and you are welcome to redistribute it under certain conditions;
+ type 'show c' for details.
+
+The hypothetical commands 'show w' and 'show c' should show the appropriate
+parts of the General Public License. Of course, the commands you use may be
+called something other than 'show w' and 'show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your school,
+if any, to sign a "copyright disclaimer" for the program, if necessary. Here
+is a sample; alter the names:
+
+ Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+ 'Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+ signature of Ty Coon, 1 April 1989

+ Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs. If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library. If this is what you want to do, use the GNU Library General Public
+License instead of this License.
+
+
+"CLASSPATH" EXCEPTION TO THE GPL
+
+Certain source files distributed by Oracle America and/or its affiliates are
+subject to the following clarification and special exception to the GPL, but
+only where Oracle has expressly included in the particular source file's header
+the words "Oracle designates this particular file as subject to the "Classpath"
+exception as provided by Oracle in the LICENSE file that accompanied this code."
+
+ Linking this library statically or dynamically with other modules is making
+ a combined work based on this library. Thus, the terms and conditions of
+ the GNU General Public License cover the whole combination.
+
+ As a special exception, the copyright holders of this library give you
+ permission to link this library with independent modules to produce an
+ executable, regardless of the license terms of these independent modules,
+ and to copy and distribute the resulting executable under terms of your
+ choice, provided that you also meet, for each linked independent module,
+ the terms and conditions of the license of that module. An independent
+ module is a module which is not derived from or based on this library. If
+ you modify this library, you may extend this exception to your version of
+ the library, but you are not obligated to do so. If you do not wish to do
+ so, delete this exception statement from your version.

+- What is Nashorn?
+
+Nashorn is a runtime environment for programs written in ECMAScript 5.1
+that runs on top of JVM.
+
+- How to find out more about ECMAScript 5.1?
+
+The specification can be found at
+
+ http://www.ecma-international.org/publications/standards/Ecma-262.htm
+
+- How to checkout sources of Nashorn project?
+
+Nashorn project uses Mercurial source code control system. You can
+download Mercurial from http://mercurial.selenic.com/wiki/Download
+
+Information about the forest extension can be found at
+
+ http://mercurial.selenic.com/wiki/ForestExtension
+
+and downlaoded using
+
+ hg clone https://bitbucket.org/gxti/hgforest
+
+You can clone Nashorn Mercurial forest using this command:
+
+ hg fclone http://hg.openjdk.java.net/nashorn/jdk8 nashorn~jdk8
+
+To update your copy of the forest (fwith the latest code:
+
+ (cd nashorn~jdk8 ; hg fpull)
+
+Or just the nashorn subdirectory with
+
+ (cd nashorn~jdk8/nashorn ; hg pull -u)
+
+To learn about Mercurial in detail, please visit http://hgbook.red-bean.com.
+
+- How to build?
+
+To build Nashorn, you need to install JDK 8. You may use the Nashorn
+forest build (recommended) or down load from java.net. You will need to
+set JAVA_HOME environmental variable to point to your JDK installation
+directory.
+
+ cd nashorn~jdk8/nashorn/make
+ ant clean; ant
+
+- How to run?
+
+Use the jjs script (see RELESE_README):
+
+ cd nashorn~jdk8/nashorn
+ sh bin/jjs <your .js file>
+
+Nashorn supports javax.script API. It is possible to drop nashorn.jar in
+class path and request for "nashorn" script engine from
+javax.script.ScriptEngineManager.
+
+Look for samples under the directory test/src/jdk/nashorn/api/scripting/.
+
+- Documentation
+
+Comprehensive development documentation is found in the Nashorn JavaDoc. You can
+build it using:
+
+ cd nashorn~jdk8/nashorn/make
+ ant javadoc
+
+after which you can view the generated documentation at dist/javadoc/index.html.
+
+- Running tests
+
+Nashorn tests are TestNG based. Running tests requires downloading the
+TestNG library and placing its jar file into the lib subdirectory:
+
+ # download and install TestNG
+ wget http://testng.org/testng-x.y.z.zip
+ unzip testng-x.y.z.zip
+ cp testng-x.y.z/testng-x.y.z.jar test/lib/testng.jar
+
+After that, you can run the tests using:
+ cd make
+ ant test
+
+You can also run the ECMA-262 test suite with Nashorn. In order to do
+that, you will need to get a copy of it and put it in
+test/script/external/test262 directory. A convenient way to do it is:
+
+ hg clone http://hg.ecmascript.org/tests/test262/ test/script/external/test262
+
+Alternatively, you can check it out elsewhere and make
+test/script/external/test262 a symbolic link to that directory. After
+you've done this, you can run the ECMA-262 tests using:
+
+ cd nashorn~jdk8/nashorn/make
+ ant test262
+
+These tests take time, so we have a parallelized runner for them that
+takes advantage of all processor cores on the computer:
+
+ cd nashorn~jdk8/nashorn/make
+ ant test262parallel
+
+- How to write your own test?
+
+Nashorn uses it's own simple test framework. Any .js file dropped under
+nashorn/test directory is considered as a test. A test file can
+optionally have .js.EXPECTED (foo.js.EXPECTED for foo.js) associated
+with it. The .EXPECTED file, if exists, should contain the output
+expected from compiling and/or running the test file.
+
+The test runner crawls these directories for .js files and looks for
+JTReg-style @foo comments to identify tests.
+
+ * @test - A test is tagged with @test.
+
+ * @test/fail - Tests that are supposed to fail (compiling, see @run/fail
+ for runtime) are tagged with @test/fail.

+The Nashorn repo is in the process of being migrated to OpenJDK and as such is
+incomplete in several areas.
+
+- The build system is not fully integrated. When complete, Nashorn will be
+installed in its proper location in the JRE.
+
+- Once integrated, the correct version of the JDK will be wrapped around
+Nashorn. In the meantime, ensure you use JDK8 b68 or later.
+
+- The jjs tool has not been implemented in binary form yet. Use "sh bin/jjs"
+(or bin/jjs.bat on windows) in the interm.
+
+- The Dynalink component is not fully integrated into Nashorn as yet, but will
+be when details are finalized.
+
+- And, finally Nashorn is still in development. To stay up to date, subscribe
+to nashorn-dev@openjdk.java.net at
+
+ http://mail.openjdk.java.net/mailman/listinfo/nashorn-dev.

+Nasgen is a tool for processing Java classes that implement native
+JavaScript objects. It does so by looking for the
+com.oracle.nashorn.objects.annotations.ScriptClass annotation and other
+annotations in that package.
+
+For each class "C", nasgen instruments the original class and generates
+two additional classes: a "C$Prototype" class for the JavaScript
+prototype object, and a "C$Constructor" class for the JavaScript
+constructor function.
+
+Each class instrumented or generated by nasgen contains a private static
+"$nasgenmap$" field of type com.oracle.nashorn.runtime.PropertyMap and
+static initializer block to initialize the field to the object's
+JavaScript properties.
+
+Members annotated with @Function, @Property, @Getter, and @Setter are
+mapped to the $Constructor, $Prototype, or main class, depending on the
+value of the annotation's 'where' field. By default, @Property, @Getter,
+and @Setter belong to the main class while @Function methods without
+explicit 'where' field belong to the $Prototype class. The @Constructor
+annotation marks a method to be invoked as JavaScript constructor.
+
+Nasgen enforces all @Function/@Getter/@Setter/@Constructor annotated
+methods to be declared as static. Static final @Property fields remain
+in the main class while other @Property fields are moved to respective
+classes depending on the annotation's 'where' value. For functions
+mapped to the $Prototype or $Constructor class, nasgen also generates
+getters and setters prefixed by G$ and S$, respectively.
+
+Nasgen-generated classes are hidden from normal ClassLoaders by giving
+them a ".clazz" file name extension instead of the standard ".class"
+extension. This allows script classes to be loaded independently by each
+Nashorn context through the com.oracle.nashorn.runtime.StructureLoader
+class loader.

+This document describes system properties that are used for internal
+debugging and instrumentation purposes, along with the system loggers,
+which are used for the same thing.
+
+This document is intended as a developer resource, and it is not
+needed as Nashorn documentation for normal usage. Flags and system
+properties described herein are subject to change without notice.
+
+=====================================
+1. System properties used internally
+=====================================
+
+This documentation of the system property flags assume that the
+default value of the flag is false, unless otherwise specified.
+
+SYSTEM PROPERTY: -Dnashorn.unstable.relink.threshold=x
+
+This property controls how many call site misses are allowed before a
+callsite is relinked with "apply" semantics to never change again.
+In the case of megamorphic callsites, this is necessary, or the
+program would spend all its time swapping out callsite targets. Dynalink
+has a default value (currently 8 relinks) for this property if it
+is not explicitly set.
+
+
+SYSTEM PROPERTY: -Dnashorn.compiler.splitter.threshold=x
+
+This will change the node weight that requires a subgraph of the IR to
+be split into several classes in order not to run out of bytecode space.
+The default value is 0x8000 (32768).
+
+
+SYSTEM PROPERTY: -Dnashorn.compiler.intarithmetic
+
+Arithmetic operations in Nashorn (except bitwise ones) typically
+coerce the operands to doubles (as per the JavaScript spec). To switch
+this off and remain in integer mode, for example for "var x = a&b; var
+y = c&d; var z = x*y;", use this flag. This will force the
+multiplication of variables that are ints to be done with the IMUL
+bytecode and the result "z" to become an int.
+
+WARNING: Note that is is experimental only to ensure that type support
+exists for all primitive types. The generated code is unsound. This
+will be the case until we do optimizations based on it. There is a CR
+in Nashorn to do better range analysis, and ensure that this is only
+done where the operation can't overflow into a wider type. Currently
+no overflow checking is done, so at the moment, until range analysis
+has been completed, this option is turned off.
+
+We've experimented by using int arithmetic for everything and putting
+overflow checks afterwards, which would recompute the operation with
+the correct precision, but have yet to find a configuration where this
+is faster than just using doubles directly, even if the int operation
+does not overflow. Getting access to a JVM intrinsic that does branch
+on overflow would probably alleviate this.
+
+There is also a problem with this optimistic approach if the symbol
+happens to reside in a local variable slot in the bytecode, as those
+are strongly typed. Then we would need to split large sections of
+control flow, so this is probably not the right way to go, while range
+analysis is. There is a large difference between integer bytecode
+without overflow checks and double bytecode. The former is
+significantly faster.
+
+
+SYSTEM PROPERTY: -Dnashorn.codegen.debug, -Dnashorn.codegen.debug.trace=<x>
+
+See the description of the codegen logger below.
+
+
+SYSTEM_PROPERTY: -Dnashorn.fields.debug
+
+See the description on the fields logger below.
+
+
+SYSTEM PROPERTY: -Dnashorn.fields.dual
+
+When this property is true, Nashorn will attempt to use primitive
+fields for AccessorProperties (currently just AccessorProperties, not
+spill properties). Memory footprint for script objects will increase,
+as we need to maintain both a primitive field (a long) as well as an
+Object field for the property value. Ints are represented as the 32
+low bits of the long fields. Doubles are represented as the
+doubleToLongBits of their value. This way a single field can be used
+for all primitive types. Packing and unpacking doubles to their bit
+representation is intrinsified by the JVM and extremely fast.
+
+While dual fields in theory runs significantly faster than Object
+fields due to reduction of boxing and memory allocation overhead,
+there is still work to be done to make this a general purpose
+solution. Research is ongoing.
+
+In the future, this might complement or be replaced by experimental
+feature sun.misc.TaggedArray, which has been discussed on the mlvm
+mailing list. TaggedArrays are basically a way to share data space
+between primitives and references, and have the GC understand this.
+
+As long as only primitive values are written to the fields and enough
+type information exists to make sure that any reads don't have to be
+uselessly boxed and unboxed, this is significantly faster than the
+standard "Objects only" approach that currently is the default. See
+test/examples/dual-fields-micro.js for an example that runs twice as
+fast with dual fields as without them. Here, the compiler, can
+determine that we are dealing with numbers only throughout the entire
+property life span of the properties involved.
+
+If a "real" object (not a boxed primitive) is written to a field that
+has a primitive representation, its callsite is relinked and an Object
+field is used forevermore for that particular field in that
+PropertyMap and its children, even if primitives are later assigned to
+it.
+
+As the amount of compile time type information is very small in a
+dynamic language like JavaScript, it is frequently the case that
+something has to be treated as an object, because we don't know any
+better. In reality though, it is often a boxed primitive is stored to
+an AccessorProperty. The fastest way to handle this soundly is to use
+a callsite typecheck and avoid blowing the field up to an Object. We
+never revert object fields to primitives. Ping-pong:ing back and forth
+between primitive representation and Object representation would cause
+fatal performance overhead, so this is not an option.
+
+For a general application the dual fields approach is still slower
+than objects only fields in some places, about the same in most cases,
+and significantly faster in very few. This is due the program using
+primitives, but we still can't prove it. For example "local_var a =
+call(); field = a;" may very well write a double to the field, but the
+compiler dare not guess a double type if field is a local variable,
+due to bytecode variables being strongly typed and later non
+interchangeable. To get around this, the entire method would have to
+be replaced and a continuation retained to restart from. We believe
+that the next steps we should go through are instead:
+
+1) Implement method specialization based on callsite, as it's quite
+frequently the case that numbers are passed around, but currently our
+function nodes just have object types visible to the compiler. For
+example "var b = 17; func(a,b,17)" is an example where two parameters
+can be specialized, but the main version of func might also be called
+from another callsite with func(x,y,"string").
+
+2) This requires lazy jitting as the functions have to be specialized
+per callsite.
+
+Even though "function square(x) { return x*x }" might look like a
+trivial function that can always only take doubles, this is not
+true. Someone might have overridden the valueOf for x so that the
+toNumber coercion has side effects. To fulfil JavaScript semantics,
+the coercion has to run twice for both terms of the multiplication
+even if they are the same object. This means that call site
+specialization is necessary, not parameter specialization on the form
+"function square(x) { var xd = (double)x; return xd*xd; }", as one
+might first think.
+
+Generating a method specialization for any variant of a function that
+we can determine by types at compile time is a combinatorial explosion
+of byte code (try it e.g. on all the variants of am3 in the Octane
+benchmark crypto.js). Thus, this needs to be lazy
+
+3) Possibly optimistic callsite writes, something on the form
+
+x = y; //x is a field known to be a primitive. y is only an object as
+far as we can tell
+
+turns into
+
+try {
+ x = (int)y;
+} catch (X is not an integer field right now | ClassCastException e) {
+ x = y;
+}
+
+Mini POC shows that this is the key to a lot of dual field performance
+in seemingly trivial micros where one unknown object, in reality
+actually a primitive, foils it for us. Very common pattern. Once we
+are "all primitives", dual fields runs a lot faster than Object fields
+only.
+
+We still have to deal with objects vs primitives for local bytecode
+slots, possibly through code copying and versioning.
+
+
+SYSTEM PROPERTY: -Dnashorn.compiler.symbol.trace=[<x>[,*]],
+ -Dnashorn.compiler.symbol.stacktrace=[<x>[,*]]
+
+When this property is set, creation and manipulation of any symbol
+named "x" will show information about when the compiler changes its
+type assumption, bytecode local variable slot assignment and other
+data. This is useful if, for example, a symbol shows up as an Object,
+when you believe it should be a primitive. Usually there is an
+explanation for this, for example that it exists in the global scope
+and type analysis has to be more conservative.
+
+Several symbols names to watch can be specified by comma separation.
+
+If no variable name is specified (and no equals sign), all symbols
+will be watched
+
+By using "stacktrace" instead of or together with "trace", stack
+traces will be displayed upon symbol changes according to the same
+semantics.
+
+
+SYSTEM PROPERTY: nashorn.lexer.xmlliterals
+
+If this property it set, it means that the Lexer should attempt to
+parse XML literals, which would otherwise generate syntax
+errors. Warning: there are currently no unit tests for this
+functionality.
+
+XML literals, when this is enabled, end up as standard LiteralNodes in
+the IR.
+
+
+SYSTEM_PROPERTY: nashorn.debug
+
+If this property is set to true, Nashorn runs in Debug mode. Debug
+mode is slightly slower, as for example statistics counters are enabled
+during the run. Debug mode makes available a NativeDebug instance
+called "Debug" in the global space that can be used to print property
+maps and layout for script objects, as well as a "dumpCounters" method
+that will print the current values of the previously mentioned stats
+counters.
+
+These functions currently exists for Debug:
+
+"map" - print(Debug.map(x)) will dump the PropertyMap for object x to
+stdout (currently there also exist functions called "embedX", where X
+is a value from 0 to 3, that will dump the contents of the embed pool
+for the first spill properties in any script object and "spill", that
+will dump the contents of the growing spill pool of spill properties
+in any script object. This is of course subject to change without
+notice, should we change the script object layout.
+
+"methodHandle" - this method returns the method handle that is used
+for invoking a particular script function.
+
+"identical" - this method compares two script objects for reference
+equality. It is a == Java comparison
+
+"dumpCounters" - will dump the debug counters' current values to
+stdout.
+
+Currently we count number of ScriptObjects in the system, number of
+Scope objects in the system, number of ScriptObject listeners added,
+removed and dead (without references).
+
+We also count number of ScriptFunctions, ScriptFunction invocations
+and ScriptFunction allocations.
+
+Furthermore we count PropertyMap statistics: how many property maps
+exist, how many times were property maps cloned, how many times did
+the property map history cache hit, prevent new allocations, how many
+prototype invalidations were done, how many time the property map
+proto cache hit.
+
+Finally we count callsite misses on a per callsite bases, which occur
+when a callsite has to be relinked, due to a previous assumption of
+object layout being invalidated.
+
+
+SYSTEM PROPERTY: nashorn.methodhandles.debug,
+nashorn.methodhandles.debug=create
+
+If this property is enabled, each MethodHandle related call that uses
+the java.lang.invoke package gets its MethodHandle intercepted and an
+instrumentation printout of arguments and return value appended to
+it. This shows exactly which method handles are executed and from
+where. (Also MethodTypes and SwitchPoints). This can be augmented with
+more information, for example, instance count, by subclassing or
+further extending the TraceMethodHandleFactory implementation in
+MethodHandleFactory.java.
+
+If the property is specialized with "=create" as its option,
+instrumentation will be shown for method handles upon creation time
+rather than at runtime usage.
+
+
+SYSTEM PROPERTY: nashorn.methodhandles.debug.stacktrace
+
+This does the same as nashorn.methodhandles.debug, but when enabled
+also dumps the stack trace for every instrumented method handle
+operation. Warning: This is enormously verbose, but provides a pretty
+decent "grep:able" picture of where the calls are coming from.
+
+See the description of the codegen logger below for a more verbose
+description of this option
+
+
+SYSTEM PROPERTY: nashorn.scriptfunction.specialization.disable
+
+There are several "fast path" implementations of constructors and
+functions in the NativeObject classes that, in their original form,
+take a variable amount of arguments. Said functions are also declared
+to take Object parameters in their original form, as this is what the
+JavaScript specification mandates.
+
+However, we often know quite a lot more at a callsite of one of these
+functions. For example, Math.min is called with a fixed number (2) of
+integer arguments. The overhead of boxing these ints to Objects and
+folding them into an Object array for the generic varargs Math.min
+function is an order of magnitude slower than calling a specialized
+implementation of Math.min that takes two integers. Specialized
+functions and constructors are identified by the tag
+@SpecializedFunction and @SpecializedConstructor in the Nashorn
+code. The linker will link in the most appropriate (narrowest types,
+right number of types and least number of arguments) specialization if
+specializations are available.
+
+Every ScriptFunction may carry specializations that the linker can
+choose from. This framework will likely be extended for user defined
+functions. The compiler can often infer enough parameter type info
+from callsites for in order to generate simpler versions with less
+generic Object types. This feature depends on future lazy jitting, as
+there tend to be many calls to user defined functions, some where the
+callsite can be specialized, some where we mostly see object
+parameters even at the callsite.
+
+If this system property is set to true, the linker will not attempt to
+use any specialized function or constructor for native objects, but
+just call the generic one.
+
+
+SYSTEM PROPERTY: nashorn.tcs.miss.samplePercent=<x>
+
+When running with the trace callsite option (-tcs), Nashorn will count
+and instrument any callsite misses that require relinking. As the
+number of relinks is large and usually produces a lot of output, this
+system property can be used to constrain the percentage of misses that
+should be logged. Typically this is set to 1 or 5 (percent). 1% is the
+default value.
+
+
+SYSTEM_PROPERTY: nashorn.profilefile=<filename>
+
+When running with the profile callsite options (-pcs), Nashorn will
+dump profiling data for all callsites to stderr as a shutdown hook. To
+instead redirect this to a file, specify the path to the file using
+this system property.
+
+
+SYSTEM_PROPERTY: nashorn.regexp.impl=[jdk|joni]
+
+This property defines the regular expression engine to be used by
+Nashorn. The default implementation is "jdk" which is based on the
+JDK's java.util.regex package. Set this property to "joni" to install
+an implementation based on Joni, the regular expression engine used by
+the JRuby project.
+
+
+===============
+2. The loggers.
+===============
+
+It is very simple to create your own logger. Use the DebugLogger class
+and give the subsystem name as a constructor argument.
+
+The Nashorn loggers can be used to print per-module or per-subsystem
+debug information with different levels of verbosity. The loggers for
+a given subsystem are available are enabled by using
+
+--log=<systemname>[:<level>]
+
+on the command line.
+
+Here <systemname> identifies the name of the subsystem to be logged
+and the optional colon and level argument is a standard
+java.util.logging.Level name (severe, warning, info, config, fine,
+finer, finest). If the level is left out for a particular subsystem,
+it defaults to "info". Any log message logged as the level or a level
+that is more important will be output to stderr by the logger.
+
+Several loggers can be enabled by a single command line option, by
+putting a comma after each subsystem/level tuple (or each subsystem if
+level is unspecified). The --log option can also be given multiple
+times on the same command line, with the same effect.
+
+For example: --log=codegen,fields:finest is equivalent to
+--log=codegen:info --log=fields:finest
+
+The subsystems that currently support logging are:
+
+
+* compiler
+
+The compiler is in charge of turning source code and function nodes
+into byte code, and installs the classes into a class loader
+controlled from the Context. Log messages are, for example, about
+things like new compile units being allocated. The compiler has global
+settings that all the tiers of codegen (e.g. Lower and CodeGenerator)
+use.s
+
+
+* codegen
+
+The code generator is the emitter stage of the code pipeline, and
+turns the lowest tier of a FunctionNode into bytecode. Codegen logging
+shows byte codes as they are being emitted, line number information
+and jumps. It also shows the contents of the bytecode stack prior to
+each instruction being emitted. This is a good debugging aid. For
+example:
+
+[codegen] #41 line:2 (f)_afc824e
+[codegen] #42 load symbol x slot=2
+[codegen] #43 {1:O} load int 0
+[codegen] #44 {2:I O} dynamic_runtime_call GT:ZOI_I args=2 returnType=boolean
+[codegen] #45 signature (Ljava/lang/Object;I)Z
+[codegen] #46 {1:Z} ifeq ternary_false_5402fe28
+[codegen] #47 load symbol x slot=2
+[codegen] #48 {1:O} goto ternary_exit_107c1f2f
+[codegen] #49 ternary_false_5402fe28
+[codegen] #50 load symbol x slot=2
+[codegen] #51 {1:O} convert object -> double
+[codegen] #52 {1:D} neg
+[codegen] #53 {1:D} convert double -> object
+[codegen] #54 {1:O} ternary_exit_107c1f2f
+[codegen] #55 {1:O} return object
+
+shows a ternary node being generated for the sequence "return x > 0 ?
+x : -x"
+
+The first number on the log line is a unique monotonically increasing
+emission id per bytecode. There is no guarantee this is the same id
+between runs. depending on non deterministic code
+execution/compilation, but for small applications it usually is. If
+the system variable -Dnashorn.codegen.debug.trace=<x> is set, where x
+is a bytecode emission id, a stack trace will be shown as the
+particular bytecode is about to be emitted. This can be a quick way to
+determine where it comes from without attaching the debugger. "Who
+generated that neg?"
+
+The --log=codegen option is equivalent to setting the system variable
+"nashorn.codegen.debug" to true.
+
+
+* lower
+
+This is the first lowering pass.
+
+Lower is a code generation pass that turns high level IR nodes into
+lower level one, for example substituting comparisons to RuntimeNodes
+and inlining finally blocks.
+
+Lower is also responsible for determining control flow information
+like end points.
+
+
+* attr
+
+The lowering annotates a FunctionNode with symbols for each identifier
+and transforms high level constructs into lower level ones, that the
+CodeGenerator consumes.
+
+Lower logging typically outputs things like post pass actions,
+insertions of casts because symbol types have been changed and type
+specialization information. Currently very little info is generated by
+this logger. This will probably change.
+
+
+* finalize
+
+This --log=finalize log option outputs information for type finalization,
+the third tier of the compiler. This means things like placement of
+specialized scope nodes or explicit conversions.
+
+
+* fields
+
+The --log=fields option (at info level) is equivalent to setting the
+system variable "nashorn.fields.debug" to true. At the info level it
+will only show info about type assumptions that were invalidated. If
+the level is set to finest, it will also trace every AccessorProperty
+getter and setter in the program, show arguments, return values
+etc. It will also show the internal representation of respective field
+(Object in the normal case, unless running with the dual field
+representation)

+<h2><span>Who is the Java Scripting API For?</span></h2>
+<span>Some useful characteristics of scripting languages
+are:</span>
+<ul>
+<li><span><b>Convenience</b>: Most scripting languages are
+dynamically typed. You can usually create new variables without
+declaring the variable type, and you can reuse variables to store
+objects of different types. Also, scripting languages tend to
+perform many type conversions automatically, for example,
+converting the number 10 to the text "10" as necessary.</span></li>
+<li><span><b>Developing rapid prototypes</b>: You can avoid the
+edit-compile-run cycle and just use edit-run!</span></li>
+<li><span><b>Application extension/customization</b>: You can
+"externalize" parts of your application - like configuration
+scripts, business logic/rules and math expressions for financial
+applications.</span></li>
+<li><span><b>"Command line" shells for applications</b> -for
+debugging, runtime/deploy time configuration etc. Most applications
+have a web-based GUI configuaration tool these days. But
+sysadmins/deployers frequently prefer command line tools. Instead
+of inventing ad-hoc scripting language for that purpose, a
+"standard" scripting language can be used.</span></li>
+</ul>
+<p><span>The Java<font size="-1"><sup>TM</sup></font> Scripting API
+is a scripting language indepedent framework for using script
+engines from Java code. With the Java Scripting API, it is possible
+to write customizable/extendable applications in the Java language
+and leave the customization scripting language choice to the end
+user. The Java application developer need not choose the extension
+language during development. If you write your application with
+JSR-223 API, then your users can use any JSR-223 compliant
+scripting language.</span></p>
+<hr>
+<span><a name="package" id="package"></a></span>
+<h2><span>Scripting Package</span></h2>
+<p><span>The Java Scripting functionality is in the <code><a href="http://docs.oracle.com/javase/6/docs/api/javax/script/package-summary.html">javax.script</a></code>
+package. This is a relatively small, simple API. The starting point
+of the scripting API is the <code>ScriptEngineManager</code> class.
+A ScriptEngineManager object can discover script engines through
+the jar file service discovery mechanism. It can also instantiate
+ScriptEngine objects that interpret scripts written in a specific
+scripting language. The simplest way to use the scripting API is as
+follows:</span></p>
+<ol>
+<li><span>Create a <code>ScriptEngineManager</code>
+object.</span></li>
+<li><span>Get a <code>ScriptEngine</code> object from the
+manager.</span></li>
+<li><span>Evaluate script using the <code>ScriptEngine</code>'s
+<code>eval</code> methods.</span></li>
+</ol>
+<p><span>Now, it is time to look at some sample code. While it is
+not mandatory, it may be useful to know a bit of JavaScript to read
+these examples.</span></p>
+<hr>
+<span><a name="examples" id="examples"></a></span>
+<h2><span>Examples</span></h2>
+<span><a name="helloworld" id="helloworld"></a></span>
+<h3><span>"Hello, World"</span></h3>
+<p><span>From the <code>ScriptEngineManager</code> instance, we
+request a JavaScript engine instance using
+<code>getEngineByName</code> method. On the script engine, the
+<code>eval</code> method is called to execute a given String as
+JavaScript code! For brevity, in this as well as in subsequent
+examples, we have not shown exception handling. There are checked
+and runtime exceptions thrown from <code>javax.script</code> API.
+Needless to say, you have to handle the exceptions
+appropriately.</span></p>
+<pre>
+<span><code>
+// <a href="source/EvalScript.java">EvalScript.java</a>
+
+import javax.script.*;
+public class EvalScript {
+ public static void main(String[] args) throws Exception {
+ // create a script engine manager
+ <span class="classref">ScriptEngineManager</span> factory = new ScriptEngineManager();
+ // create a JavaScript engine
+ <span class="classref">ScriptEngine</span> engine = factory.<span class="methodref">getEngineByName</span>("nashorn");
+ // evaluate JavaScript code from String
+ engine.<span class="methodref">eval</span>("print('Hello, World')");
+ }
+}
+</code></span>
+</pre>
+<hr>
+<a name="evalfile" id="evalfile"></a>
+<h3>Evaluating a Script File</h3>
+<p>In this example, we call the <code>eval</code> method that
+accepts <code>java.io.Reader</code> for the input source. The
+script read by the given reader is executed. This way it is
+possible to execute scripts from files, URLs and resources by
+wrapping the relevant input stream objects as readers.</p>
+<pre>
+<code>
+// <a href="source/EvalFile.java">EvalFile.java</a>
+
+import javax.script.*;
+
+public class EvalFile {
+ public static void main(String[] args) throws Exception {
+ // create a script engine manager
+ <span class="classref">ScriptEngineManager</span> factory = new ScriptEngineManager();
+ // create JavaScript engine
+ <span class="classref">ScriptEngine</span> engine = factory.<span class="methodref">getEngineByName</span>("nashorn");
+ // evaluate JavaScript code from given file - specified by first argument
+ engine.<span class="methodref">eval</span>(new java.io.FileReader(args[0]));
+ }
+}
+</code>
+</pre>
+Let us assume that we have the file named <a href="source/test.js">test.js</a> with the
+following text:
+<pre><code>
+print("This is hello from test.js");
+</code>
+</pre>
+We can run the above Java as
+<pre><code>
+java EvalFile test.js
+</code>
+</pre>
+<hr>
+<a name="scriptvars" id="scriptvars"></a>
+<h3>Script Variables</h3>
+<p>When you embed script engines and scripts with your Java
+application, you may want to expose your application objects as
+global variables to scripts. This example demonstrates how you can
+expose your application objects as global variables to a script. We
+create a <code>java.io.File</code> in the application and expose
+the same as a global variable with the name "file". The script can
+access the variable - for example, it can call public methods on
+it. Note that the syntax to access Java objects, methods and fields
+is dependent on the scripting language. JavaScript supports the
+most "natural" Java-like syntax.</p>
+<pre><code>
+// <a href="source/ScriptVars.java">ScriptVars.java</a>
+
+import javax.script.*;
+import java.io.*;
+
+public class ScriptVars {
+ public static void main(String[] args) throws Exception {
+ ScriptEngineManager manager = new ScriptEngineManager();
+ ScriptEngine engine = manager.getEngineByName("nashorn");
+
+ File f = new File("test.txt");
+ // expose File object as variable to script
+ engine.<span class="methodref">put</span>("file", f);
+
+ // evaluate a script string. The script accesses "file"
+ // variable and calls method on it
+ engine.eval("print(file.getAbsolutePath())");
+ }
+}
+
+</code>
+</pre>
+<hr>
+<a name="invoke" id="invoke"></a>
+<h3>Invoking Script Functions and Methods</h3>
+<p>Sometimes you may want to call a specific scripting function
+repeatedly - for example, your application menu functionality might
+be implemented by a script. In your menu's action event handler you
+may want to call a specific script function. The following example
+demonstrates invoking a specific script function from Java
+code.</p>
+<pre><code>
+// <a href="source/InvokeScriptFunction.java">InvokeScriptFunction.java</a>
+
+import javax.script.*;
+
+public class InvokeScriptFunction {
+ public static void main(String[] args) throws Exception {
+ ScriptEngineManager manager = new ScriptEngineManager();
+ ScriptEngine engine = manager.getEngineByName("nashorn");
+
+ // JavaScript code in a String
+ String script = "function hello(name) { print('Hello, ' + name); }";
+ // evaluate script
+ engine.eval(script);
+
+ // <code>javax.script.Invocable</code> is an optional interface.
+ // Check whether your script engine implements it or not!
+ // Note that the JavaScript engine implements Invocable interface.
+ <span class="classref">Invocable</span> inv = (Invocable) engine;
+
+ // invoke the global function named "hello"
+ inv.<span class="methodref">invokeFunction</span>("hello", "Scripting!!" );
+ }
+}
+
+</code>
+</pre>
+<p>If your scripting language is object based (like JavaScript) or
+object-oriented, then you can invoke a script method on a script
+object.</p>
+<pre><code>
+// <a href="source/InvokeScriptMethod.java">InvokeScriptMethod.java</a>
+
+import javax.script.*;
+
+public class InvokeScriptMethod {
+ public static void main(String[] args) throws Exception {
+ ScriptEngineManager manager = new ScriptEngineManager();
+ ScriptEngine engine = manager.getEngineByName("nashorn");
+
+ // JavaScript code in a String. This code defines a script object 'obj'
+ // with one method called 'hello'.
+ String script = "var obj = new Object(); obj.hello = function(name) { print('Hello, ' + name); }";
+ // evaluate script
+ engine.eval(script);
+
+ // <code>javax.script.Invocable</code> is an optional interface.
+ // Check whether your script engine implements or not!
+ // Note that the JavaScript engine implements Invocable interface.
+ <span class="classref">Invocable</span> inv = (Invocable) engine;
+
+ // get script object on which we want to call the method
+ Object obj = engine.<span class="methodref">get</span>("obj");
+
+ // invoke the method named "hello" on the script object "obj"
+ inv.<span class="methodref">invokeMethod</span>(obj, "hello", "Script Method !!" );
+ }
+}
+
+</code>
+</pre>
+<hr>
+<a name="interfaces" id="interfaces"></a>
+<h3>Implementing Java Interfaces by Scripts</h3>
+<p>Instead of calling specific script functions from Java,
+sometimes it is convenient to implement a Java interface by script
+functions or methods. Also, by using interfaces we can avoid having
+to use the <code>javax.script</code> API in many places. We can get
+an interface implementor object and pass it to various Java APIs.
+The following example demonstrates implementing the
+<code>java.lang.Runnable</code> interface with a script.</p>
+<pre><code>
+// <a href="source/RunnableImpl.java">RunnableImpl.java</a>
+
+import javax.script.*;
+
+public class RunnableImpl {
+ public static void main(String[] args) throws Exception {
+ ScriptEngineManager manager = new ScriptEngineManager();
+ ScriptEngine engine = manager.getEngineByName("nashorn");
+
+ // JavaScript code in a String
+ String script = "function run() { print('run called'); }";
+
+ // evaluate script
+ engine.eval(script);
+
+ <span class="classref">Invocable</span> inv = (Invocable) engine;
+
+ // get Runnable interface object from engine. This interface methods
+ // are implemented by script functions with the matching name.
+ Runnable r = inv.<span class="methodref">getInterface</span>(Runnable.class);
+
+ // start a new thread that runs the script implemented
+ // runnable interface
+ Thread th = new Thread(r);
+ th.start();
+ th.join();
+ }
+}
+</code>
+</pre>
+<p>If your scripting language is object-based or object-oriented,
+it is possible to implement a Java interface by script methods on
+script objects. This avoids having to call script global functions
+for interface methods. The script object can store the "state"
+associated with the interface implementor.</p>
+<pre><code>
+// <a href="source/RunnableImplObject.java">RunnableImplObject.java</a>
+
+import javax.script.*;
+
+public class RunnableImplObject {
+ public static void main(String[] args) throws Exception {
+ ScriptEngineManager manager = new ScriptEngineManager();
+ ScriptEngine engine = manager.getEngineByName("nashorn");
+
+ // JavaScript code in a String
+ String script = "var obj = new Object(); obj.run = function() { print('run method called'); }";
+
+ // evaluate script
+ engine.eval(script);
+
+ // get script object on which we want to implement the interface with
+ Object obj = engine.<span class="methodref">get</span>("obj");
+
+ <span class="classref">Invocable</span> inv = (Invocable) engine;
+
+ // get Runnable interface object from engine. This interface methods
+ // are implemented by script methods of object 'obj'
+ Runnable r = inv.<span class="methodref">getInterface</span>(obj, Runnable.class);
+
+ // start a new thread that runs the script implemented
+ // runnable interface
+ Thread th = new Thread(r);
+ th.start();
+ th.join();
+ }
+}
+</code>
+</pre>
+<hr>
+<a name="scopes" id="scopes"></a>
+<h3>Multiple Scopes for Scripts</h3>
+<p>In the <a href="#scriptvars">script variables</a> example, we
+saw how to expose application objects as script global variables.
+It is possible to expose multiple global "scopes" for scripts. A
+single scope is an instance of <code>javax.script.Bindings</code>.
+This interface is derived from <code>java.util.Map<String,
+Object></code>. A scope a set of name-value pairs where name is
+any non-empty, non-null String.
+<code>javax.script.ScriptContext</code> interface supports multiple
+scopes with associated Bindings for each
+scope. By default, every script engine has a default script
+context. The default script context has atleast one scope called
+"ENGINE_SCOPE". Various scopes supported by a script context are
+available through <code>getScopes</code> method.</p>
+<pre><code>
+// <a href="source/MultiScopes.java">MultiScopes.java</a>
+
+import javax.script.*;
+
+public class MultiScopes {
+ public static void main(String[] args) throws Exception {
+ ScriptEngineManager manager = new ScriptEngineManager();
+ ScriptEngine engine = manager.getEngineByName("nashorn");
+
+ engine.put("x", "hello");
+ // print global variable "x"
+ engine.eval("print(x);");
+ // the above line prints "hello"
+
+ // Now, pass a different script context
+ <span class="classref">ScriptContext</span> newContext = new <span class="classref">SimpleScriptContext</span>();
+ newContext.setBindings(engine.createBindings(), ScriptContext.ENGINE_SCOPE);
+ <span class="classref">Bindings</span> engineScope = newContext.<span class="methodref">getBindings</span>(ScriptContext.ENGINE_SCOPE);
+
+ // add new variable "x" to the new engineScope
+ engineScope.<span class="methodref">put</span>("x", "world");
+
+ // execute the same script - but this time pass a different script context
+ engine.eval("print(x);", newContext);
+ // the above line prints "world"
+ }
+}
+
+</code>

+<h2>JavaScript Script Engine</h2>
+<p>Oracle's implementation of JDK 8 is co-bundled with the Nashorn ECMAScript
+script engine.
+<hr>
+<a name="jstojava" id="jstojava"></a>
+<h2>JavaScript to Java Communication</h2>
+<p>For the most part, accessing Java classes, objects and methods
+is straightforward. In particular field and method access from
+JavaScript is the same as it is from Java. We highlight important
+aspects of JavaScript Java access here.
+The following examples are JavaScript snippets accessing Java. This
+section requires knowledge of JavaScript. This section can be
+skipped if you are planning to use some other JSR-223 scripting
+language rather than JavaScript.</p>
+<hr>
+<a name="jsjavaclass" id=jsjavalass"></a>
+<h3>Accessing Java Classes</h3>
+<pre>
+<code>
+// <a href="source/javatypes.js">javatypes.js</a>
+
+ var arrayListType = Java.type("java.util.ArrayList")
+ var intType = Java.type("int")
+ var stringArrayType = Java.type("java.lang.String[]")
+ var int2DArrayType = Java.type("int[][]")
+</code>
+</pre>
+
+Note that the name of the type is always a string for a fully qualified name. You can use any of these types to create new instances, e.g.:
+
+<pre><code>
+ var anArrayList = new Java.type("java.util.ArrayList")
+</code></pre>
+
+or
+
+<pre><code>
+ var ArrayList = Java.type("java.util.ArrayList")
+ var anArrayList = new ArrayList
+ var anArrayListWithSize = new ArrayList(16)
+</code></pre>
+
+In the special case of inner classes, you need to use the JVM fully qualified name, meaning using $ sign in the class name:
+
+<pre><code>
+ var ftype = Java.type("java.awt.geom.Arc2D$Float")
+</code></pre>
+
+
+However, once you retrieved the outer class, you can access the inner class as a property on it:
+
+<pre><code>
+ var arctype = Java.type("java.awt.geom.Arc2D")
+ var ftype = arctype.Float
+</code></pre>
+<p>
+You can access both static and non-static inner classes. If you want to create an instance of a non-static inner class, remember to pass an instance of its outer class as the first argument to the constructor.
+</p>
+<hr>
+<a name="jsimport" id="jsimport"></a>
+<h3>Importing Java Packages, Classes</h3>
+<p>The built-in functions <code>importPackage</code> (in compatibility script) and
+<code>importClass</code> can be used to import Java packages and
+classes.</p>
+<pre><code>
+
+// <a href="source/importpackageclass.js">importpackageclass.js</a>
+
+// load compatibility script
+load("nashorn:mozilla_compat.js");
+// Import Java packages and classes
+// like import package.*; in Java
+<span class="functionref">importPackage</span>(java.awt);
+// like import java.awt.Frame in Java
+<span class="functionref">importClass</span>(java.awt.Frame);
+// Create Java Objects by "new ClassName"
+var frame = new java.awt.Frame("hello");
+// Call Java public methods from script
+frame.setVisible(true);
+// Access "JavaBean" properties like "fields"
+print(frame.title);
+</code>
+</pre>
+<p>The <span class="objectref">Packages</span> global variable can
+be used to access Java packages. Examples:
+<code>Packages.java.util.Vector</code>,
+<code>Packages.javax.swing.JFrame</code>. Please note that "java"
+is a shortcut for "Packages.java". There are equivalent shortcuts
+for javax, org, edu, com, net prefixes, so pratically all JDK
+platform classes can be accessed without the "Packages" prefix.</p>
+<p>Note that java.lang is not imported by default (unlike Java)
+because that would result in conflicts with JavaScript's built-in
+Object, Boolean, Math and so on.</p>
+<p><code>importPackage</code> and <code>importClass</code>
+functions "pollute" the global variable scope of JavaScript. To
+avoid that, you may use <span class="functionref">JavaImporter</span>.</p>
+<pre><code>
+
+// <a href="source/javaimporter.js">javaimporter.js</a>
+
+// create JavaImporter with specific packages and classes to import
+
+var SwingGui = new <span class="functionref">JavaImporter</span>(javax.swing,
+ javax.swing.event,
+ javax.swing.border,
+ java.awt.event);
+with (SwingGui) {
+ // within this 'with' statement, we can access Swing and AWT
+ // classes by unqualified (simple) names.
+
+ var mybutton = new JButton("test");
+ var myframe = new JFrame("test");
+}
+
+</code>
+</pre>
+<hr>
+<a name="jsarrays" id="jsarrays"></a>
+<h3>Creating, Converting and Using Java Arrays</h3>
+<p>While creating a Java object is the same as in Java, to create
+Java arrays in JavaScript we can use Java reflection
+explicitly. But once created the element access or length access is
+the same as in Java. Also, a script array can be used when a Java
+method expects a Java array (auto conversion). So in most cases we
+don't have to create Java arrays explicitly.</p>
+<pre><code>
+// <a href="source/javaarray.js">javaarray.js</a>
+
+// create Java String array of 5 elements
+var a = java.lang.reflect.Array.newInstance(java.lang.String.class, 5);
+
+// Accessing elements and length access is by usual Java syntax
+a[0] = "scripting is great!";
+print(a.length);
+print(a[0]);
+</code>
+</pre>
+<p>
+It is also possible to convert between JavaScript and Java arrays.
+Given a JavaScript array and a Java type, <code>Java.toJavaArray</code> returns a Java array with the same initial contents, and with the specified component type.
+</p>
+<pre><code>
+ var anArray = [1, "13", false]
+ var javaIntArray = Java.toJavaArray(anArray, "int")
+ print(javaIntArray[0]) // prints 1
+ print(javaIntArray[1]) // prints 13, as string "13" was converted to number 13 as per ECMAScript ToNumber conversion
+ print(javaIntArray[2]) // prints 0, as boolean false was converted to number 0 as per ECMAScript ToNumber conversion
+</code></pre>
+<p>
+Given a Java array or Collection, <code>Java.toJavaScriptArray</code> returns a JavaScript array with a shallow copy of its contents. Note that in most cases, you can use Java arrays and lists natively in Nashorn; in cases where for some reason you need to have an actual JavaScript native array (e.g. to work with the array comprehensions functions), you will want to use this method.i
+</p>
+<pre><code>

+<h3>Implementing Java Interfaces</h3>
+<p>A Java interface can be implemented in JavaScript by using a
+Java anonymous class-like syntax:</p>
+<pre><code>
+// <a href="source/runnable.js">runnable.js</a>
+
+var r = new java.lang.Runnable() {
+ run: function() {
+ print("running...\n");
+ }
+};
+
+// "r" can be passed to Java methods that expect java.lang.Runnable
+var th = new java.lang.Thread(r);
+th.start();
+th.join();
+</code>
+</pre>
+<p>When an interface with a single method is expected, you can pass
+a script function directly.(auto conversion)</p>
+<pre><code>
+// <a href="source/samfunc.js">samfunc.js</a>
+
+function func() {
+ print("I am func!");
+}
+
+// pass script function for java.lang.Runnable argument
+var th = new java.lang.Thread(func);
+th.start();
+th.join();
+</code>
+</pre>
+<hr>
+<a name="jsextend" id="jsextend"></a>
+<h3>Extending Java classes</h3>
+<p>
+If a Java class is abstract, you can instantiate an anonymous subclass of it using an argument list that is applicable to any of its public or protected constructors, but inserting a JavaScript object with functions properties that provide JavaScript implementations of the abstract methods. If method names are overloaded, the JavaScript function will provide implementation for all overloads. E.g.:
+</p>
+
+<pre><code>
+ var TimerTask = Java.type("java.util.TimerTask")
+ var task = new TimerTask({ run: function() { print("Hello World!") } })
+</code></pre>
+
+Nashorn supports a syntactic extension where a "new" expression followed by an argument is identical to invoking the constructor and passing the argument to it, so you can write the above example also as:
+
+<pre><code>
+ var task = new TimerTask {
+ run: function() {
+ print("Hello World!")
+ }
+ }
+</code></pre>
+
+which is very similar to Java anonymous inner class definition. On the other hand, if the type is an abstract type with a single abstract method (commonly referred to as a "SAM type") or all abstract methods it has share the same overloaded name), then instead of an object, you can just pass a function, so the above example can become even more simplified to:
+
+<pre><code>
+ var task = new TimerTask(function() { print("Hello World!") })
+</code></pre>
+
+<p>
+Note that in every one of these cases if you are trying to instantiate an abstract class that has constructors that take some arguments, you can invoke those simply by specifying the arguments after the initial implementation object or function.
+</p>
+<p>
+The use of functions can be taken even further; if you are invoking a Java method that takes a SAM type, you can just pass in a function object, and Nashorn will know what you meant:
+</p>
+<code><pre>
+ Java.type("java.util.Timer")
+ timer.schedule(function() { print("Hello World!") })
+</code></pre>
+
+Here, <code>Timer.schedule()</code> expects a <code>TimerTask</code> as its argument, so Nashorn creates an instance of a TimerTask subclass and uses the passed function to implement its only abstract method, run(). In this usage though, you can't use non-default constructors; the type must be either an interface, or must have a protected or public no-arg constructor.
+
+<p>
+To extend a concrete Java class, you have to use <code>Java.extend</code> function.
+<code>Java.extend</code> returns a type object for a subclass of the specified Java class (or implementation of the specified interface) that acts as a script-to-Java adapter for it.
+</p>
+<pre><code>
+// <a href="source/javaextend.js">javaextend.js</a>
+
+var ArrayList = Java.type("java.util.ArrayList")
+var ArrayListExtender = Java.extend(ArrayList)
+var printSizeInvokedArrayList = new ArrayListExtender() {
+ size: function() { print("size invoked!"); }
+}
+var printAddInvokedArrayList = new ArrayListExtender() {
+ add: function(x, y) {
+ if(typeof(y) === "undefined") {
+ print("add(e) invoked!");
+ } else {
+ print("add(i, e) invoked!");
+ }
+ }
+};
+printSizeInvokedArrayList.size();
+printAddInvokedArrayList.add(33, 33);
+</code></pre>
+<hr>
+<a name="jsoverload" id="jsoverload"></a>
+<h3>Overload Resolution</h3>
+<p>Java methods can be overloaded by argument types. In Java,
+overload resolution occurs at compile time (performed by javac).
+When calling Java methods from a script, the script
+interpreter/compiler needs to select the appropriate method. With
+the JavaScript engine, you do not need to do anything special - the
+correct Java method overload variant is selected based on the
+argument types. But, sometimes you may want (or have) to explicitly
+select a particular overload variant.</p>
+<pre><code>
+// <a href="source/overload.js">overload.js</a>
+
+var out = java.lang.System.out;
+
+// select a particular print function
+out["println(java.lang.Object)"]("hello");
+</code>
+</pre>

+<h2>Implementing Your Own Script Engine</h2>
+<p>We will not cover implementation of JSR-223 compliant script
+engines in detail. Minimally, you need to implement the
+<code>javax.script.ScriptEngine</code> and
+<code>javax.script.ScriptEngineFactory</code> interfaces. The
+abstract class <code>javax.script.AbstractScriptEngine</code>
+provides useful defaults for a few methods of the
+<code>ScriptEngine</code> interface.</p>
+<p>Before starting to implement a JSR-223 engine, you may want to
+check <a href="http://java.net/projects/Scripting">http://java.net/projects/Scripting</a>
+project. This project maintains JSR-223 implementations for many
+popular open source scripting languages.</p>

+/**
+ * The linker for {@link RelinkableCallSite} objects. Users of it (scripting frameworks and language runtimes) have to
+ * create a linker using the {@link DynamicLinkerFactory} and invoke its link method from the invokedynamic bootstrap
+ * methods to set the target of all the call sites in the code they generate. Usual usage would be to create one class
+ * per language runtime to contain one linker instance as:
+ *
+ * <pre>
+ * class MyLanguageRuntime {
+ * private static final GuardingDynamicLinker myLanguageLinker = new MyLanguageLinker();
+ * private static final DynamicLinker dynamicLinker = createDynamicLinker();
+ *
+ * private static DynamicLinker createDynamicLinker() {
+ * final DynamicLinkerFactory factory = new DynamicLinkerFactory();
+ * factory.setPrioritizedLinker(myLanguageLinker);
+ * return factory.createLinker();
+ * }
+ *
+ * public static CallSite bootstrap(MethodHandles.Lookup caller, String name, MethodType type) {
+ * return dynamicLinker.link(new MonomorphicCallSite(CallSiteDescriptorFactory.create(lookup, name, type)));
+ * }
+ * }
+ * </pre>
+ *
+ * Note how there are three components you will need to provide here:
+ * <ul>
+ * <li>You're expected to provide a {@link GuardingDynamicLinker} for your own language. If your runtime doesn't
+ * have its own language and/or object model (i.e. it's a generic scripting shell), you don't need to implement a
+ * dynamic linker; you would simply not invoke the {@code setPrioritizedLinker} method on the factory, or even better,
+ * simply use {@link DefaultBootstrapper}.</li>
+ * <li>The performance of the programs can depend on your choice of the class to represent call sites. The above
+ * example used {@link MonomorphicCallSite}, but you might want to use {@link ChainedCallSite} instead. You'll need to
+ * experiment and decide what fits your language runtime the best. You can subclass either of these or roll your own if
+ * you need to.</li>
+ * <li>You also need to provide {@link CallSiteDescriptor}s to your call sites. They are immutable objects that contain
+ * all the information about the call site: the class performing the lookups, the name of the method being invoked, and
+ * the method signature. The library has a default {@link CallSiteDescriptorFactory} for descriptors that you can use,
+ * or you can create your own descriptor classes, especially if you need to add further information (values passed in
+ * additional parameters to the bootstrap method) to them.</li>
+ * </ul>

+ * A linker for POJOs. Normally used as the ultimate fallback linker by the {@link DynamicLinkerFactory} so it is given

+ * <ul>
+ * <li>expose all public methods of form {@code setXxx()}, {@code getXxx()}, and {@code isXxx()} as property setters and
+ * getters for {@code dyn:setProp} and {@code dyn:getProp} operations;</li>
+ * <li>expose all public methods for invocation through {@code dyn:callMethod} operation;</li>
+ * <li>expose all public methods for retrieval for {@code dyn:getMethod} operation; the methods thus retrieved can then
+ * be invoked using {@code dyn:call};</li>
+ * <li>expose all public fields as properties, unless there are getters or setters for the properties of the same name;</li>
+ * <li>expose {@code dyn:getLength}, {@code dyn:getElem} and {@code dyn:setElem} on native Java arrays, as well as
+ * {@link java.util.List} and {@link java.util.Map} objects; ({@code dyn:getLength} works on any
+ * {@link java.util.Collection});</li>
+ * <li>expose a virtual property named {@code length} on Java arrays;</li>
+ * <li>expose {@code dyn:new} on instances of {@link StaticClass} as calls to constructors, including those static class
+ * objects that represent Java arrays (their constructors take a single {@code int} parameter representing the length of
+ * the array to create);</li>
+ * <li>expose static methods, fields, and properties of classes in a similar manner to how instance method, fields, and
+ * properties are exposed, on {@link StaticClass} objects.</li>
+ * <li>expose a virtual property named {@code static} on instances of {@link java.lang.Class} to access their
+ * {@link StaticClass}.</li>
+ * </ul>
+ * <p><strong>Overloaded method resolution</strong> is performed automatically for property setters, methods, and
+ * constructors. Additionally, manual overloaded method selection is supported by having a call site specify a name for
+ * a method that contains an explicit signature, i.e. {@code dyn:getMethod:parseInt(String,int)}. You can use
+ * non-qualified class names in such signatures regardless of those classes' packages, they will match any class with
+ * the same non-qualified name. You only have to use a fully qualified class name in case non-qualified class names
+ * would cause selection ambiguity (that is extremely rare).</p>
+ * <p><strong>Variable argument invocation</strong> is handled for both methods and constructors.</p>
+ * <p>Currently, only public fields and methods are supported. Any Lookup objects passed in the
+ * {@link LinkRequest}s are ignored and {@link MethodHandles#publicLookup()} is used instead.</p>

+ * Implements the name mangling and demangling as specified by John Rose's
+ * <a href="https://blogs.oracle.com/jrose/entry/symbolic_freedom_in_the_vm" target="_blank">"Symbolic Freedom in the
+ * VM"</a> article. It is recommended that implementers of languages on the JVM uniformly adopt this for symbolic
+ * interoperability between languages. Normally, you would mangle the names as you're generating bytecode, and then
+ * demangle them when you're creating {@link CallSiteDescriptor} objects. Note that you are expected to mangle
+ * individual tokens, and not the whole name at the call site, i.e. the colon character normally separating the tokens
+ * is never mangled. I.e. you wouldn't mangle {@code dyn:getProp:color} into {@code dyn\!getProp\!color}, but you would
+ * mangle {@code dyn:getProp:color$} into {@code dyn:getProp:\=color\%} (only mangling the individual token containing
+ * the symbol {@code color$}). {@link CallSiteDescriptorFactory#tokenizeName(String)} (and by implication, all call site
+ * descriptors it creates) will automatically perform demangling on the passed names. If you use this factory, or you
+ * have your own way of creating call site descriptors, but you still delegate to this method of the default factory
+ * (it is recommended that you do), then you have demangling handled for you already, and only need to ensure that you
+ * mangle the names when you're emitting them in the bytecode.

+/**
+ * The interface responsible for speaking to ASM, emitting classes,
+ * fields and methods.
+ * <p>
+ * This file contains the ClassEmitter, which is the master object
+ * responsible for writing byte codes. It utilizes a MethodEmitter
+ * for method generation, which also the NodeVisitors own, to keep
+ * track of the current code generator and what it is doing.
+ * <p>
+ * There is, however, nothing stopping you from using this in a
+ * completely self contained environment, for example in ObjectGenerator
+ * where there are no visitors or external hooks.
+ * <p>
+ * MethodEmitter makes it simple to generate code for methods without
+ * having to do arduous type checking. It maintains a type stack
+ * and will pick the appropriate operation for all operations sent to it
+ * We also allow chained called to a MethodEmitter for brevity, e.g.
+ * it is legal to write _new(className).dup() or
+ * load(slot).load(slot2).xor().store(slot3);
+ * <p>
+ * If running with assertions enabled, any type conflict, such as different
+ * bytecode stack sizes or operating on the wrong type will be detected
+ * and an error thrown.
+ * <p>
+ * There is also a very nice debug interface that can emit formatted
+ * bytecodes that have been written. This is enabled by setting the
+ * environment "nashorn.codegen.debug" to true, or --log=codegen:{@literal <level>}
+ * <p>
+ * A ClassEmitter implements an Emitter - i.e. it needs to have
+ * well defined start and end calls for whatever it is generating. Assertions
+ * detect if this is not true
+ *

+/**
+ * This class is the implementation of the Nashorn-specific global object named {@code JSAdapter}. It can be
+ * thought of as the {@link java.lang.reflect.Proxy} equivalent for JavaScript. NativeJSAdapter calls specially named
+ * JavaScript methods on an adaptee object when property access/update/call/new/delete is attempted on it. Example:
+ *<pre>
+ * var y = {
+ * __get__ : function (name) { ... }
+ * __has__ : function (name) { ... }
+ * __put__ : function (name, value) {...}
+ * __call__ : function (name, arg1, arg2) {...}
+ * __new__ : function (arg1, arg2) {...}
+ * __delete__ : function (name) { ... }
+ * __getIds__ : function () { ... }
+ * };
+ *
+ * var x = new JSAdapter(y);
+ *
+ * x.i; // calls y.__get__
+ * x.foo(); // calls y.__call__
+ * new x(); // calls y.__new__
+ * i in x; // calls y.__has__
+ * x.p = 10; // calls y.__put__
+ * delete x.p; // calls y.__delete__
+ * for (i in x) { print(i); } // calls y.__getIds__
+ * </pre>
+ * <p>
+ * JavaScript caller of adapter object is isolated from the fact that the property access/mutation/deletion are really
+ * calls to JavaScript methods on adaptee.
+ * </p>
+ * <p>
+ * JSAdapter constructor can optionally receive an "overrides" object. Properties of overrides object is copied to
+ * JSAdapter instance. When user accessed property is one of these, then adaptee's methods like {@code __get__},
+ * {@code __put__} etc. are not called for those. This can be used to make certain "preferred" properties that can be
+ * accessed in the usual/faster way avoiding proxy mechanism. Example:
+ * </p>
+ * <pre>
+ * var x = new JSAdapter({ foo: 444, bar: 6546 }) {
+ * __get__: function(name) { return name; }
+ * };
+ *
+ * x.foo; // 444 directly retrieved without __get__ call
+ * x.bar = 'hello'; // "bar" directly set without __put__ call
+ * x.prop // calls __get__("prop") as 'prop' is not overridden
+ * </pre>
+ * It is possible to pass a specific prototype for JSAdapter instance by passing three arguments to JSAdapter
+ * constructor. So exact signature of JSAdapter constructor is as follows:
+ * <pre>
+ * JSAdapter([proto], [overrides], adaptee);
+ * </pre>
+ * Both proto and overrides are optional - but adaptee is not. When proto is not passed {@code JSAdapter.prototype} is
+ * used.

+ * used to represent Java types in Nashorn is not {@link java.lang.Class} but rather {@link StaticClass}. They are
+ * the objects that you can use with the {@code new} operator to create new instances of the class as well as to
+ * access static members of the class. In Nashorn, {@code Class} objects are just regular Java objects that aren't
+ * treated specially. Instead of them, {@link StaticClass} instances - which we sometimes refer to as "Java type
+ * objects" are used as constructors with the {@code new} operator, and they expose static fields, properties, and
+ * methods. While this might seem confusing at first, it actually closely matches the Java language: you use a
+ * different expression (e.g. {@code java.io.File}) as an argument in "new" and to address statics, and it is
+ * distinct from the {@code Class} object (e.g. {@code java.io.File.class}). Below we cover in details the
+ * properties of the type objects.
+ * </p>
+ * <p><b>Constructing Java objects</b></p>
+ * Examples:
+ * <pre>
+ * var arrayListType = Java.type("java.util.ArrayList")
+ * var intType = Java.type("int")
+ * var stringArrayType = Java.type("java.lang.String[]")
+ * var int2DArrayType = Java.type("int[][]")
+ * </pre>
+ * Note that the name of the type is always a string for a fully qualified name. You can use any of these types to
+ * create new instances, e.g.:
+ * <pre>
+ * var anArrayList = new Java.type("java.util.ArrayList")
+ * </pre>
+ * or
+ * <pre>
+ * var ArrayList = Java.type("java.util.ArrayList")
+ * var anArrayList = new ArrayList
+ * var anArrayListWithSize = new ArrayList(16)
+ * </pre>
+ * In the special case of inner classes, you need to use the JVM fully qualified name, meaning using {@code $} sign
+ * in the class name:
+ * <pre>
+ * var ftype = Java.type("java.awt.geom.Arc2D$Float")
+ * </pre>
+ * However, once you retrieved the outer class, you can access the inner class as a property on it:
+ * <pre>
+ * var arctype = Java.type("java.awt.geom.Arc2D")
+ * var ftype = arctype.Float
+ * </pre>
+ * <p>
+ * You can access both static and non-static inner classes. If you want to create an instance of a non-static
+ * inner class, remember to pass an instance of its outer class as the first argument to the constructor.
+ * </p>
+ * <p>
+ * If the type is abstract, you can instantiate an anonymous subclass of it using an argument list that is
+ * applicable to any of its public or protected constructors, but inserting a JavaScript object with functions
+ * properties that provide JavaScript implementations of the abstract methods. If method names are overloaded, the
+ * JavaScript function will provide implementation for all overloads. E.g.:
+ * </p>
+ * <pre>
+ * var TimerTask = Java.type("java.util.TimerTask")
+ * var task = new TimerTask({ run: function() { print("Hello World!") } })
+ * </pre>
+ * <p>
+ * Nashorn supports a syntactic extension where a "new" expression followed by an argument is identical to
+ * invoking the constructor and passing the argument to it, so you can write the above example also as:
+ * </p>
+ * <pre>
+ * var task = new TimerTask {
+ * run: function() {
+ * print("Hello World!")
+ * }
+ * }
+ * </pre>
+ * <p>
+ * which is very similar to Java anonymous inner class definition. On the other hand, if the type is an abstract
+ * type with a single abstract method (commonly referred to as a "SAM type") or all abstract methods it has share
+ * the same overloaded name), then instead of an object, you can just pass a function, so the above example can
+ * become even more simplified to:
+ * </p>
+ * <pre>
+ * var task = new TimerTask(function() { print("Hello World!") })
+ * </pre>
+ * <p>
+ * Note that in every one of these cases if you are trying to instantiate an abstract class that has constructors
+ * that take some arguments, you can invoke those simply by specifying the arguments after the initial
+ * implementation object or function.
+ * </p>
+ * <p>The use of functions can be taken even further; if you are invoking a Java method that takes a SAM type,
+ * you can just pass in a function object, and Nashorn will know what you meant:
+ * </p>
+ * <pre>
+ * var timer = new Java.type("java.util.Timer")
+ * timer.schedule(function() { print("Hello World!") })
+ * </pre>
+ * <p>
+ * Here, {@code Timer.schedule()} expects a {@code TimerTask} as its argument, so Nashorn creates an instance of a
+ * {@code TimerTask} subclass and uses the passed function to implement its only abstract method, {@code run()}. In
+ * this usage though, you can't use non-default constructors; the type must be either an interface, or must have a
+ * protected or public no-arg constructor.
+ * </p>
+ * <p>
+ * You can also subclass non-abstract classes; for that you will need to use the {@link #extend(Object, Object...)}
+ * method.
+ * </p>
+ * <p><b>Accessing static members</b></p>
+ * Examples:
+ * <pre>
+ * var File = Java.type("java.io.File")
+ * var pathSep = File.pathSeparator
+ * var tmpFile1 = File.createTempFile("abcdefg", ".tmp")
+ * var tmpFile2 = File.createTempFile("abcdefg", ".tmp", new File("/tmp"))
+ * </pre>
+ * Actually, you can even assign static methods to variables, so the above example can be rewritten as:
+ * <pre>
+ * var File = Java.type("java.io.File")
+ * var createTempFile = File.createTempFile
+ * var tmpFile1 = createTempFile("abcdefg", ".tmp")
+ * var tmpFile2 = createTempFile("abcdefg", ".tmp", new File("/tmp"))
+ * </pre>
+ * If you need to access the actual {@code java.lang.Class} object for the type, you can use the {@code class}
+ * property on the object representing the type:
+ * <pre>
+ * var File = Java.type("java.io.File")
+ * var someFile = new File("blah")
+ * print(File.class === someFile.getClass()) // prints true
+ * </pre>
+ * Of course, you can also use the {@code getClass()} method or its equivalent {@code class} property on any
+ * instance of the class. Other way round, you can use the synthetic {@code static} property on any
+ * {@code java.lang.Class} object to retrieve its type-representing object:
+ * <pre>
+ * var File = Java.type("java.io.File")
+ * print(File.class.static === File) // prints true
+ * </pre>
+ * <p><b>{@code instanceof} operator</b></p>
+ * The standard ECMAScript {@code instanceof} operator is extended to recognize Java objects and their type objects:
+ * <pre>
+ * var File = Java.type("java.io.File")
+ * var aFile = new File("foo")
+ * print(aFile instanceof File) // prints true
+ * print(aFile instanceof File.class) // prints false - Class objects aren't type objects.
+ * </pre>
+ * @param self not used
+ * @param objTypeName the object whose JS string value represents the type name. You can use names of primitive Java
+ * types to obtain representations of them, and you can use trailing square brackets to represent Java array types.
+ * @return the object representing the named type
+ * @throws ClassNotFoundException if the class is not found
+ */

+ * <li>If the Java method is overloaded (as in the above example {@code List.add()}), then your JavaScript adapter

+ * <li>You can't invoke {@code super.*()} from adapters for now.</li>
+ * </ul>
+ * @param self not used
+ * @param types the original types. The caller must pass at least one Java type object of class {@link StaticClass}
+ * representing either a public interface or a non-final public class with at least one public or protected
+ * constructor. If more than one type is specified, at most one can be a class and the rest have to be interfaces.
+ * Invoking the method twice with exactly the same types in the same order will return the same adapter
+ * class, any reordering of types or even addition or removal of redundant types (i.e. interfaces that other types
+ * in the list already implement/extend, or {@code java.lang.Object} in a list of types consisting purely of
+ * interfaces) will result in a different adapter class, even though those adapter classes are functionally

+/**
+ * An object that exposes Java packages and classes as its properties. Packages are exposed as objects that have further
+ * sub-packages and classes as their properties. Normally, three instances of this class are exposed as built-in objects
+ * in Nashorn: {@code "Packages"}, {@code "java"}, and {@code "javax"}. Typical usages are:
+ * <pre>
+ * var list = new java.util.ArrayList()
+ * var sprocket = new Packages.com.acme.Sprocket()
+ * </pre>
+ * or you can store the type objects in a variable for later reuse:
+ * <pre>
+ * var ArrayList = java.util.ArrayList
+ * var list = new ArrayList
+ * </pre>
+ * You can also use {@link NativeJava#type(Object, Object)} to access Java classes. These two statements are mostly
+ * equivalent:
+ * <pre>
+ * var listType1 = java.util.ArrayList
+ * var listType2 = Java.type("java.util.ArrayList")
+ * </pre>
+ * The difference is that {@code Java.type()} will throw an error if the class does not exist, while the first
+ * expression will return an empty object, as it must treat all non-existent classes as potentially being further
+ * subpackages. As such, {@code Java.type()} has the potential to catch typos earlier. A further difference is that
+ * {@code Java.type()} doesn't recognize {@code .} (dot) as the separator between outer class name and inner class name,
+ * it only recognizes the dollar sign. These are equivalent:
+ * <pre>
+ * var ftype1 = java.awt.geom.Arc2D$Float
+ * var ftype2 = java.awt.geom.Arc2D.Float
+ * var ftype3 = Java.asType("java.awt.geom.Arc2D$Float")

+/**
+ * Immutable hash map implementation for properties. Properties are keyed on strings.
+ * Copying and cloning is avoided by relying on immutability.
+ * <p>
+ * When adding an element to a hash table, only the head of a bin list is updated, thus
+ * an add only requires the cloning of the bins array and adding an element to the head
+ * of the bin list. Similarly for removal, only a portion of a bin list is updated.
+ * <p>
+ * A separate chronological list is kept for quick generation of keys and values, and,
+ * for rehashing.
+ * <p>
+ * Details:
+ * <p>
+ * The main goal is to be able to retrieve properties from a map quickly, keying on
+ * the property name (String.) A secondary, but important goal, is to keep maps
+ * immutable, so that a map can be shared by multiple objects in a context.
+ * Sharing maps allows objects to be categorized as having similar properties, a
+ * fact that call site guards rely on. In this discussion, immutability allows us
+ * to significantly reduce the amount of duplication we have in our maps.
+ * <p>
+ * The simplest of immutable maps is a basic singly linked list. New properties
+ * are simply added to the head of the list. Ancestor maps are not affected by the
+ * addition, since they continue to refer to their own head. Searching is done by
+ * walking linearly though the elements until a match is found, O(N).
+ * <p>
+ * A hash map can be thought of as an optimization of a linked list map, where the
+ * linked list is broken into fragments based on hashCode(key) . An array is use
+ * to quickly reference these fragments, indexing on hashCode(key) mod tableSize
+ * (tableSize is typically a power of 2 so that the mod is a fast masking
+ * operation.) If the size of the table is sufficient large, then search time
+ * approaches O(1). In fact, most bins in a hash table are typically empty or
+ * contain a one element list.
+ * <p>
+ * For immutable hash maps, we can think of the hash map as an array of the shorter
+ * linked list maps. If we add an element to the head of one of those lists, it
+ * doesn't affect any ancestor maps. Thus adding an element to an immutable hash
+ * map only requires cloning the array and inserting an element at the head of one
+ * of the bins.
+ * <p>
+ * Using Java HashMaps we don't have enough control over the entries to allow us to
+ * implement this technique, so we are forced to clone the entire hash map.
+ * <p>
+ * Removing elements is done similarly. We clone the array and then only modify
+ * the bin containing the removed element. More often than not, the list contains
+ * only one element (or is very short), so this is not very costly. When the list
+ * has several items, we need to clone the list portion prior to the removed item.
+ * <p>
+ * Another requirement of property maps is that we need to be able to gather all
+ * properties in chronological (add) order. We have been using LinkedHashMap to
+ * provide this. For the implementation of immutable hash map, we use a singly
+ * linked list that is linked in reverse chronological order. This means we simply
+ * add new entries to the head of the list. If we need to work with the list in
+ * forward order, it's simply a matter of allocating an array (size is known) and
+ * back filling in reverse order. Removal of elements from the chronological list
+ * is trickier. LinkedHashMap uses a doubly linked list to give constant time
+ * removal. Immutable hash maps can't do that and maintain immutability. So we
+ * manage the chronological list the same way we manage the bins, cloning up to the
+ * point of removal. Don't panic. This cost is more than offset by the cost of
+ * cloning an entire LinkedHashMap. Plus removal is far more rare than addition.
+ * <p>
+ * One more optimization. Maps with a small number of entries don't use the hash
+ * map at all, the chronological list is used instead.
+ * <p>
+ * So the benefits from immutable arrays are; fewer objects and less copying. For
+ * immutable hash map, when no removal is involved, the number of elements per
+ * property is two (bin + chronological elements). For LinkedHashMap it is one
+ * (larger element) times the number of maps that refer to the property. For
+ * immutable hash map, addition is constant time. For LinkedHashMap it's O(N+C)
+ * since we have to clone the older map.

+ * operations can be found in the <a href="https://github.com/szegedi/dynalink/wiki/User-Guide-0.4">Dynalink User Guide</a>,
+ * but we'll show few examples here:
+ * <ul>
+ * <li>Get a named property with fixed name:
+ * <pre>
+ * MethodHandle getColor = Boostrap.createDynamicInvoker("dyn:getProp:color", Object.class, Object.class);
+ * Object obj = ...; // somehow obtain the object
+ * Object color = getColor.invokeExact(obj);
+ * </pre>
+ * </li>
+ * <li>Get a named property with variable name:
+ * <pre>
+ * MethodHandle getProperty = Boostrap.createDynamicInvoker("dyn:getElem", Object.class, Object.class, String.class);
+ * Object obj = ...; // somehow obtain the object
+ * Object color = getProperty.invokeExact(obj, "color");
+ * Object shape = getProperty.invokeExact(obj, "shape");
+ * MethodHandle getNumProperty = Boostrap.createDynamicInvoker("dyn:getElem", Object.class, Object.class, int.class);
+ * Object elem42 = getNumProperty.invokeExact(obj, 42);
+ * </pre>
+ * </li>
+ * <li>Set a named property with fixed name:
+ * <pre>
+ * MethodHandle setColor = Boostrap.createDynamicInvoker("dyn:setProp:color", void.class, Object.class, Object.class);
+ * Object obj = ...; // somehow obtain the object
+ * setColor.invokeExact(obj, Color.BLUE);
+ * </pre>
+ * </li>
+ * <li>Set a property with variable name:
+ * <pre>
+ * MethodHandle setProperty = Boostrap.createDynamicInvoker("dyn:setElem", void.class, Object.class, String.class, Object.class);
+ * Object obj = ...; // somehow obtain the object
+ * setProperty.invokeExact(obj, "color", Color.BLUE);
+ * setProperty.invokeExact(obj, "shape", Shape.CIRCLE);
+ * </pre>
+ * </li>
+ * <li>Call a function on an object; two-step variant. This is the actual variant used by Nashorn-generated code:
+ * <pre>
+ * MethodHandle findFooFunction = Boostrap.createDynamicInvoker("dyn:getMethod:foo", Object.class, Object.class);
+ * Object obj = ...; // somehow obtain the object
+ * Object foo_fn = findFooFunction.invokeExact(obj);
+ * MethodHandle callFunctionWithTwoArgs = Boostrap.createDynamicInvoker("dyn:call", Object.class, Object.class, Object.class, Object.class, Object.class);
+ * // Note: "call" operation takes a function, then a "this" value, then the arguments:
+ * Object foo_retval = callFunctionWithTwoArgs.invokeExact(foo_fn, obj, arg1, arg2);
+ * </pre>
+ * </li>
+ * <li>Call a function on an object; single-step variant. Although Nashorn doesn't use this variant and never
+ * emits any INVOKEDYNAMIC instructions with {@code dyn:getMethod}, it still supports this standard Dynalink
+ * operation:
+ * <pre>
+ * MethodHandle callFunctionFooWithTwoArgs = Boostrap.createDynamicInvoker("dyn:callMethod:foo", Object.class, Object.class, Object.class, Object.class);
+ * Object obj = ...; // somehow obtain the object
+ * Object foo_retval = callFunctionFooWithTwoArgs.invokeExact(obj, arg1, arg2);
+ * </pre>
+ * </li>
+ * </ul>
+ * Few additional remarks:
+ * <ul>
+ * <li>Just as Nashorn works with any Java object, the invokers returned from this method can also be applied to
+ * arbitrary Java objects in addition to Nashorn JavaScript objects.</li>
+ * <li>For invoking a named function on an object, you can also use the {@link InvokeByName} convenience class.</li>
+ * <li>For Nashorn objects {@code getElem}, {@code getProp}, and {@code getMethod} are handled almost identically,
+ * since JavaScript doesn't distinguish between different kinds of properties on an object. Either can be used with
+ * fixed property name or a variable property name. The only significant difference is handling of missing
+ * properties: {@code getMethod} for a missing member will link to a potential invocation of
+ * {@code __noSuchMethod__} on the object, {@code getProp} for a missing member will link to a potential invocation
+ * of {@code __noSuchProperty__}, while {@code getElem} for a missing member will link to an empty getter.</li>
+ * <li>In similar vein, {@code setElem} and {@code setProp} are handled identically on Nashorn objects.</li>
+ * <li>There's no rule that the variable property identifier has to be a {@code String} for {@code getProp/setProp}
+ * and {@code int} for {@code getElem/setElem}. You can declare their type to be {@code int}, {@code double},
+ * {@code Object}, and so on regardless of the kind of the operation.</li>
+ * <li>You can be as specific in parameter types as you want. E.g. if you know that the receiver of the operation
+ * will always be {@code ScriptObject}, you can pass {@code ScriptObject.class} as its parameter type. If you happen
+ * to link to a method that expects different types, (you can use these invokers on POJOs too, after all, and end up
+ * linking with their methods that have strongly-typed signatures), all necessary conversions allowed by either Java
+ * or JavaScript will be applied: if invoked methods specify either primitive or wrapped Java numeric types, or
+ * {@code String} or {@code boolean/Boolean}, then the parameters might be subjected to standard ECMAScript
+ * {@code ToNumber}, {@code ToString}, and {@code ToBoolean} conversion, respectively. Less obviously, if the
+ * expected parameter type is a SAM type, and you pass a JavaScript function, a proxy object implementing the SAM
+ * type and delegating to the function will be passed. Linkage can often be optimized when linkers have more
+ * specific type information than "everything can be an object".</li>
+ * <li>You can also be as specific in return types as you want. For return types any necessary type conversion
+ * available in either Java or JavaScript will be automatically applied, similar to the process described for
+ * parameters, only in reverse direction: if you specify any either primitive or wrapped Java numeric type, or
+ * {@code String} or {@code boolean/Boolean}, then the return values will be subjected to standard ECMAScript
+ * {@code ToNumber}, {@code ToString}, and {@code ToBoolean} conversion, respectively. Less obviously, if the return
+ * type is a SAM type, and the return value is a JavaScript function, a proxy object implementing the SAM type and
+ * delegating to the function will be returned.</li>

+ * value = obj.toJSON(key)

+ * In practice, you can have stronger type assumptions if it makes sense for your code, just remember that you must use

+ * site - that would increase the risk of them becoming megamorphic or otherwise hard to optimize by the JVM. Even if

+/**
+ * <p>A factory class that generates adapter classes. Adapter classes allow implementation of Java interfaces and
+ * extending of Java classes from JavaScript. For every combination of a superclass to extend and interfaces to
+ * implement (collectively: "original types"), exactly one adapter class is generated that extends the specified
+ * superclass and implements the specified interfaces.
+ * </p><p>
+ * The adapter class is generated in a new secure class loader that inherits Nashorn's protection domain, and has either
+ * one of the original types' class loader or the Nashorn's class loader as its parent - the parent class loader
+ * is chosen so that all the original types and the Nashorn core classes are visible from it (as the adapter will have
+ * constant pool references to ScriptObject and ScriptFunction classes). In case none of the candidate class loaders has
+ * visibility of all the required types, an error is thrown.
+ * </p><p>
+ * For every protected or public constructor in the extended class, the adapter class will have one or two public
+ * constructors (visibility of protected constructors in the extended class is promoted to public). In every case, for
+ * every original constructor, a new constructor taking a trailing ScriptObject argument preceded by original
+ * constructor arguments is present on the adapter class. When such a constructor is invoked, the passed ScriptObject's
+ * member functions are used to implement and/or override methods on the original class, dispatched by name. A single
+ * JavaScript function will act as the implementation for all overloaded methods of the same name. When methods on an
+ * adapter instance are invoked, the functions are invoked having the ScriptObject passed in the instance constructor as
+ * their "this". Subsequent changes to the ScriptObject (reassignment or removal of its functions) are not reflected in
+ * the adapter instance; the method implementations are bound to functions at constructor invocation time.
+ * {@code java.lang.Object} methods {@code equals}, {@code hashCode}, and {@code toString} can also be overridden. The
+ * only restriction is that since every JavaScript object already has a {@code toString} function through the
+ * {@code Object.prototype}, the {@code toString} in the adapter is only overridden if the passed ScriptObject has a
+ * {@code toString} function as its own property, and not inherited from a prototype. All other adapter methods can be
+ * implemented or overridden through a prototype-inherited function of the ScriptObject passed to the constructor too.
+ * </p><p>
+ * If the original types collectively have only one abstract method, or have several of them, but all share the
+ * same name, an additional constructor is provided for every original constructor; this one takes a ScriptFunction as
+ * its last argument preceded by original constructor arguments. This constructor will use the passed function as the
+ * implementation for all abstract methods. For consistency, any concrete methods sharing the single abstract method
+ * name will also be overridden by the function. When methods on the adapter instance are invoked, the ScriptFunction is
+ * invoked with {@code null} as its "this".
+ * </p><p>
+ * For adapter methods that return values, all the JavaScript-to-Java conversions supported by Nashorn will be in effect
+ * to coerce the JavaScript function return value to the expected Java return type.
+ * </p><p>
+ * Since we are adding a trailing argument to the generated constructors in the adapter class, they will never be
+ * declared as variable arity, even if the original constructor in the superclass was declared as variable arity. The
+ * reason we are passing the additional argument at the end of the argument list instead at the front is that the
+ * source-level script expression <code>new X(a, b) { ... }</code> (which is a proprietary syntax extension Nashorn uses
+ * to resemble Java anonymous classes) is actually equivalent to <code>new X(a, b, { ... })</code>.
+ * </p><p>
+ * You normally don't use this class directly, but rather either create adapters from script using
+ * {@link NativeJava#extend(Object, Object...)}, using the {@code new} operator on abstract classes and interfaces (see
+ * {@link NativeJava#type(Object, Object)}), or implicitly when passing script functions to Java methods expecting SAM
+ * types.
+ * </p>

+The recommended way to use Nashorn is through the <a href="http://jcp.org/en/jsr/detail?id=223" target="_top">JSR-223
+"Scripting for the Java Platform"</a> APIs found in the {@link javax.script} package. Usually, you'll obtain a
+{@link javax.script.ScriptEngine} instance for Nashorn using:
+<pre>
+import javax.script.*;
+...
+ScriptEngine nashornEngine = new ScriptEngineManager().getEngineByName("nashorn");
+</pre>
+and then use it just as you would any other JSR-223 script engine. See
+<a href="jdk/nashorn/api/scripting/package-summary.html">{@code jdk.nashorn.api.scripting}</a> package
+for details.
+<p>
+<h1>Compatibility</h1>
+Nashorn is 100% compliant with the <a href="http://www.ecma-international.org/publications/standards/Ecma-262.htm"
+target="_top">ECMA-262 Standard, Edition 5.1</a>. It requires a Java Virtual Machine that implements the
+<a href="http://jcp.org/en/jsr/detail?id=292" target="_top">JSR-292 "Supporting Dynamically Typed Languages on the Java
+Platform"</a> specification (often referred to as "invokedynamic"), as well as the already mentioned JSR-223.
+<h1>Interoperability with the Java platform</h1>
+<p>
+In addition to being a 100% ECMAScript 5.1 runtime, Nashorn provides features for interoperability of the ECMAScript
+programs with the Java platform. In general, any Java object put into the script engine's context will be visible from
+the script. In terms of the standard, such Java objects are not considered "native objects", but rather "host objects",
+as defined in section 4.3.8. This distinction allows certain semantical differences in handling them compared to native
+objects. For most purposes, Java objects behave just as native objects do: you can invoke their methods, get and set
+their properties. In most cases, though, you can't add arbitrary properties to them, nor can you remove existing
+properties.
+<p>
+<h2>Java collection handling</h2>
+<p>
+Native Java arrays and {@link java.util.List}s support indexed access to their elements through the property accessors,
+and {@link java.util.Map}s support both property and element access through both dot and square-bracket property
+accessors, with the difference being that dot operator gives precedence to object properties (its fields and properties
+defined as {@code getXxx} and {@code setXxx} methods) while the square bracket operator gives precedence to map
+elements. Native Java arrays expose the {@code length} property.
+<p>
+<h2>ECMAScript primitive types</h2>
+<p>
+ECMAScript primitive types for number, string, and boolean are represented with {@link java.lang.Number},
+{@link java.lang.CharSequence}, and {@link java.lang.Boolean} objects. While the most often used number type is
+{@link java.lang.Double} and the most often used string type is {@link java.lang.String}, don't rely on it as various
+internal optimizations cause other subclasses of {@code Number} and internal implementations of {@code CharSequence} to
+be used.
+<p>
+<h2>Type conversions</h2>
+<p>
+When a method on a Java object is invoked, the arguments are converted to the formal parameter types of the Java method
+using all allowed ECMAScript conversions. This can be surprising, as in general, conversions from string to number will
+succeed according to Standard's section 9.3 "ToNumber" and so on; string to boolean, number to boolean, Object to
+number, Object to string all work. Note that if the Java method's declared parameter type is {@code java.lang.Object},
+Nashorn objects are passed without any conversion whatsoever; specifically if the JavaScript value being passed is of
+primitive string type, you can only rely on it being a {@code java.lang.CharSequence}, and if the value is a number, you
+can only rely on it being a {@code java.lang.Number}. If the Java method declared parameter type is more specific (e.g.
+{@code java.lang.String} or {@code java.lang.Double}), then Nashorn will of course ensure the required type is passed.
+<p>
+<h2>SAM types</h2>
+<p>
+As a special extension when invoking Java methods, ECMAScript function objects can be passed in place of an argument
+whose Java type is so-called "single abstract method" or "SAM" type. While this name usually covers single-method
+interfaces, Nashorn is a bit more versatile, and it recognizes a type as a SAM type if all its abstract methods are
+overloads of the same name, and it is either an interface, or it is an abstract class with
+a no-arg constructor. The type itself must be public, while the constructor and the methods can be either public or
+protected. If there are multiple abstract overloads of the same name, the single function will serve as the shared
+implementation for all of them, <em>and additionally it will also override any non-abstract methods of the same name</em>.
+This is done to be consistent with the fact that ECMAScript does not have the concept of overloaded methods.
+<p>
+<h2>The {@code Java} object</h2>
+Nashorn exposes a non-standard global object named {@code Java} that is the primary API entry point into Java
+platform-specific functionality. You can use it to create instances of Java classes, convert from Java arrays to native
+arrays and back, and so on. The methods on the objects are directly implemented by public static methods on the class
+<a href="jdk/nashorn/internal/objects/NativeJava.html">{@code NativeJava}</a>, see that class for details on what
+functionality is available.
+<h2>Representations of Java types</h2>
+The method <a href="jdk/nashorn/internal/objects/NativeJava.html#type(java.lang.Object,%20java.lang.Object)">
+{@code Java.type(typeName)}</a> takes a name of a type, and returns an object representing a Java type. You can
+use that object to both create new instances of Java classes, as well as to access static fields and methods on them.
+The type object is distinct from the {@code java.lang.Class} object, which represents the reflective run-time type
+identity and doesn't carry i.e. static members. Again, see the link for {@code NativeJava} above for details.
+<h2>Other non-standard built-in objects</h2>
+In addition to {@code Java}, Nashorn also exposes some other non-standard built-in objects:
+<a href="jdk/nashorn/internal/objects/NativeJSAdapter.html">{@code JSAdapter}</a>,
+<a href="jdk/nashorn/internal/objects/NativeJavaImporter.html">{@code JavaImporter},
+<a href="jdk/nashorn/internal/runtime/NativeJavaPackage.html">{@code Packages}.</a>

+Nashorn tests are TestNG based. Running tests requires downloading the TestNG
+library and placing its jar file into the lib subdirectory:
+
+ # download and install TestNG
+ wget http://testng.org/testng-x.y.z.zip
+ unzip testng-x.y.z.zip
+ cp testng-x.y.z/testng-x.y.z.jar lib/testng.jar
+
+ # run tests
+ cd ..
+ ant test
+
+This will fail with a message like
+
+ taskdef class org.testng.TestNGAntTask cannot be found
+
+if the TestNG jar file is not installed properly or if the wrong
+version is present. (Check build.xml to find the version of TestNG
+that is required.) Only the jar file is necessary. The unzipped
+hierarchy can be removed.
+
+We have tested using TestNG 6.7 as well ad TestNG 6.8. TestNG 6.7's jar file
+is also available as part of jtreg 4.1 b05 which can be downloaded at
+http://download.java.net/openjdk/jtreg/
+
+ECMAScript script test framework:
+
+* Test tags for test framework:
+
+The test runner crawls these directories for .js files and looks for JTReg-style
+@foo comments to identify tests.
+
+ * @test - A test is tagged with @test.
+
+ * @test/fail - Tests that are supposed to fail (compiling, see @run/fail
+ for runtime) are tagged with @test/fail.
+
+ * @test/compile-error - Test expects compilation to fail, compares
+ output.
+
+ * @test/warning - Test expects compiler warnings, compares output.
+
+ * @test/nocompare - Test expects to compile [and/or run?]
+ successfully(may be warnings), does not compare output.
+
+ * @subtest - denotes necessary file for a main test file; itself is not
+ a test.
+
+ * @run - A test that should be run is also tagged with @run (otherwise
+ the test runner only compiles the test).
+
+ * @runif - A test that should be run only if a specific System property
+ is defined (Example: @runif external.v8)
+
+ * @run/fail - A test that should compile but fail with a runtime error.
+
+ * @run/param - specify runtime arguments to script.
+
+ * @run/ignore-std-error - script may produce output on stderr, ignore
+ this output.
+
+ * @compilearg \ - pass arg to compiler, sample.
+
+/**
+ * @compilearg --dump-ir-graph
+ * @test/warning

+Section 16 of ECMAScript 5.1 spec details a set of "early errors". Early
+errors should be reported before running any line of the script containing
+such error(s). Examples include syntax error, errors in regexp literals etc.
+This directory contains tests to check early errors are reported as early
+errors. Each test starts with a print call -- the output from print should
+not be seen in expected output. If seen, early errors are reported late.
