The test is
     nsk/jdi/stress/serial/heapwalking002

See for example nightly result:

Also, test
      nsk/jdi/VMOutOfMemoryException/VMOutOfMemoryException001
has been seen to fail with the same error.

At least so far, the failure has only been seen wihen the debuggee is run with -XX:+UseParallelOldGC.
The failure is intermittent.

Update: This original sighting occurred in the 2008.07.21 nightly
and used HSX-14-B01 bits. That is after the fix for 6539517 was
available so there is still some issue with the Parallel collectors
at this point in time.
Test
nsk/jdi/ObjectReference/referringObjects/referringObjects003
failed with the same assertion during PIT for hs14b08.

Link to the log:
http://sqeweb.sfbay.sun.com/nfs/comp/vm/misc/results/vm/gtee/HSX/PIT/VM/14/b08/jdk7b41/fastdebug/vm/windows-i586/client/comp/windows-i586_client_comp_nsk.jdi.testlist/ResultDir/referringObjects003/referringObjects003.log

Since test was run on windows with flag '-client' SerialGC should be used, so looks like this failure isn't specific for -XX:+UseParallelOldGC.

Update: This sighting occurred in the HSX-14-B08 PIT so the
bug introduced by 6711316 is present in the GC framework
collectors. It is very likely that this sighting is fixed by
the work on 6862295.
Another sighting in nightly testing for another test:

New nsk.quick-jdi failures (from 2008.12.17)
* nsk/jdi/stress/serial/mixed001
        This test failed the following assertion on Win32 Server VM
        (machine cheesepuff):

            Internal Error (src/share/vm/prims/jvmtiTagMap.cpp:280)
            Error: assert(orig_key != 0,"jni weak reference cleared!!")

        This failure mode is covered by the following bug:

            6729714 4/4 nsk/jdi/stress/serial/heapwalking002 fails

        I will copy this entry to 6729714.

Update: This sighting occurred in the 2008.12.17 nightly so the
bug introduced by 6711316 is present in the GC framework
collectors. It is very likely that this sighting is fixed by
the work on 6862295.
nsk/jdi/stress/serial/heapwalking002 continues to fail in
Parallel GC, but with different failure modes:

Nightly search of Parallel GC did not find any failures for this test:

Looks like nightly data goes back to 2008.08.01 so this failure
didn't show up outside of HSX-14-B08 PIT.

Nightly search of Parallel GC found no valid failures for this test:

    nsk/jdi/stress/serial/mixed001

but but it did find one general timeout.
