----------------------------------------

The tests fail reporting that JVMTI_ERROR_UNATTACHED_THREAD is
returned when GetCurrentThreadCpuTimerInfo or GetCurrentThreadCpuTime
are invoked in callbacks of Heap iteration functions.

This contradicts to the spec of following timer functions
   GetCurrentThreadCpuTimerInfo
   GetCurrentThreadCpuTime
   GetTimerInfo
   GetTime
which says:
   This function may be called from the callbacks to the Heap
   iteration functions, or from the event handles for the
   GarbageCollectionStart, GarbageCollectionFinish, and
   ObjectFree events.

Steps to reproduce a failure of nsk/jvmti/IterateOverHeap/iterheap007:

  cd /net/jano.sfbay/export/disk20/GammaBase/Bugs/<this bug number>
  sh build.sh $JAVA_HOME [-g] [-d64]
  sh run.sh $JAVA_HOME [-g] [-v] [JAVA_OPTS]
where
    -d64 - build for 64-bit solaris-sparcv9
    -g - build for or run with java_g binaries
    -v - run in verbose mode
    
Here is test output on Solaris:
-------------------------------------------------------------------------------
$ sh run.sh $JAVA_HOME -v

The tests will be available in next r27 release of testbase.

The test
  nsk/jvmti/scenarios/allocation/AP10/ap10t001
fails due to this bug too.
