+/**
+ *
+ *  @bug 6224700
+ *  @summary ReferenceType.nestedTypes() is too slow
+ *  @author jjh
+ *
+ *  @run build TestScaffold VMConnection TargetListener TargetAdapter
+ *  @run compile -g AnyDebuggeeTest.java
+ *  @run main 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.
