/**
*
* @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.
