intermittent memory access violation at the test 'jck12a011'

HS 2.0-rc1B intermittently crashes while executing the test 'jck12a011'
under WinNT 4.0 SP4 in -Xmided mode. I executed this test manually 7
times and observed 2 crashes.

On the crash, popup window is displayed with the following error message:

    Windows Says:
    -------------
    java.exe -- Application Error
    The instruction at "0x080b06fe" referenced memory at "0x00000000".
    The memory could not be "read".

When I pressed 'CANCEL' button to start the VC++ 6.0 Debugger, it
complains at start:

    Debugger Says:
    --------------
    Unhandled exception in java.exe (JVM.DLL): 0xC0000005: Access Violation.

The test 'jck12a011' belongs to the 'testbase_nsk' testbase, and its sources
be found in the directory:
    /net/sqesvr/vsn/testbase/testbase_nsk/src/nsk/stress/jck12a/jck12a011

To execute this test follow these instructions:

    1. Create some temporary directory, to say C:\TEMP\jck12a011,
       and make this directory your current directory:
           cd C:\TEMP\jck12a011

    2. Copy the test's sources into this directory. You need to copy
       only the file 'jck12a011.java', and the files 'jck12a011.cfg'
       and 'jck12a011.README' are optional.

    3. Also copy into the current directory the stress-wrapper needed to
       execute the test. The wrapper is the 'StressTest.java' file found
       in the directory:
           /new/sqesvr/vsn/testbase/testbase_nsk/src/stress/share

    4. Create 'classes' subdirectory for the wrapper's class-files you will
       need to compile:
           mkdir classes

    5. Mount to the drive L: the NFS directory:
        /usr/local/java
       (it is available as \\grinder\local-java for NT machines)

    6. Setup the CLASSPATH to provide the test with JavaTest 2.0 tool
       and JCK 1.2a pre-compiled API tests:
           set CLASSPATH=.;.\classes;L:\sqe-tools2.0\javatest.jar;L:\jck1.2\JCK-runtime-api-12a\classes

    7. Compile the wrapper with JDK 1.2, JDK 1.2.2 or JDK 1.3 compiler:
           javac -d .\classes StressTest.java

    8. Compile the test with JDK 1.2, JDK 1.2.2 or JDK 1.3 compiler:
           javac jck12a011.java

    9. Execute the test several times to reproduce the failure:
           java jck12a011 2>log
