/** * * @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.
