The Hotspot VM (build 1.4.1-beta-b10) intermittently fails the following
test from testbase_nsk:

    nsk/jvmdi/events/framepop002

The test fails also with 1.4.0-fcs, but works fine with 1.3.1-fcs.

The test do some nesting/recursive calls watching frame pop
events to be uniquely identified by thread/class/method/frame_depth.
      
This is some sort of regression test for the following bugs:

    4335224 Bug 4245697 not completely fixed jevent.u.frame.frame incorrect
    4504077 java: dbx should not hold on to a frameid after thread suspension
    4510383 The method GetCurrentFrame returns a bad frameid for JNI frames

To reproduce the bug run in GammaBase/Bugs/<this bug number> directory:

    sh doit.sh <JAVA_HOME>

Running the test usually outputs:

java version "1.4.1-beta"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.1-beta-b10)
Java HotSpot(TM) Client VM (build 1.4.1-beta-b10, mixed mode)

Frame pop does not match any entry:
