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