| 26 | * @bug 6224700 |
| 27 | * @summary ReferenceType.nestedTypes() is too slow |
| 28 | * @author jjh |
| 29 | * |
| 30 | * @run build TestScaffold VMConnection TargetListener TargetAdapter |
| 31 | * @run compile -g AnyDebuggeeTest.java |
| 32 | * @run main AnyDebuggeeeTest |
| 33 | * |
| 34 | * This test is intended to be run manually to investigate behaviors; |
| 35 | * it is not an actual test of any specific functionality, it just |
| 36 | * allows you to run the debugger part of this test on any debuggee. |
| 37 | * As set up, it prints the time to find all nested types and all |
| 38 | * subclasses in the debuggee, and so can be used to verify the |
| 39 | * fix for 6224700. |
| 40 | * |
| 41 | * For other investigations, edit this test to do whatever you want. |
| 42 | * To run this test do this: |
| 43 | * runregress -no AnyDebuggeeTest <cmd line options> |
| 44 | * where <cmd line options> are the options to be used to |
| 45 | * launch the debuggee, with the classname prefixed with @@. |
| 46 | * For example, this would run java2d demo as the debuggee: |
| 47 | * runregress -no AnyDebuggeeTest -classpath $jdkDir/demo/jfc/Java2D/Java2Demo.jar \ |
| 48 | * -client @@java2d.Java2Demo' |
| 49 | * If <cmd line options> is not specified, then the AnyDebuggeeTarg class below |
| 50 | * is run as the debuggee. |
