--------------------------------------
Test : nsk/jvmti/scenarios/sampling/SP02/sp02t001
TestBase : testbase_vm
VM : ServerVM (32- and 64-bit)
Mode : -Xmixed, -Xcomp
Platform : sparc, sparcv9
OS : SunOS 5.8
JDK : 1.5.1-b10
----------------------------------------
The test will be available in release 21 of testbase_vm.

The following JVMTI thread and stack frame functions:

    SuspendThread
    SuspendThreadList
    GetStackTrace
    GetFrameCount

hang when called from agent thread in several JVMTI tests.

Here is fragment of the test trace:

  <...>
  - sp02t001.c, 72: Testcase #1: check status of not suspended threads
  - sp02t001.c, 231: thread #0 (threadRunning):
  - sp02t001.c, 243: >> NSK_CPP_STUB3(GetFrameCount, jvmti, threadsDesc[i].thread, &frameCount)
  <test hangs>

This failure occurs only with ServerVM on solaris-sparc platform
in -Xmixed and -Xcomp modes against Tiger-b10.

The failure does not occur with ServerVM in -Xint mode or with ClientVM,
It was not revealed also on any platform other than solaris-sparc.

After hanging test is not killed by pressing Ctrl-C on console.

To reproduce the failure:
  cd /net/sqesvr.sfbay/export/vsn/GammaBase/Bugs/<this bug number>
  sh build.sh $JAVA_HOME [-g]
  sh run.sh $JAVA_HOME [-g] [-v] [-t] -server -Xmixed
where
    -g - run test with java_g binaries
    -v - run test in verbose mode
    -t - trace test execution

Here is full test log in "-server -Xmixed" mode:
