        Run the WTK/MMAPI midi tck test.
        It will crash the VM.
        WTK/MMAPI now has a workaround. The sequencer is not closed.

        An unexpected exception has been detected in native code outside the VM.
        Unexpected Signal : EXCEPTION_ACCESS_VIOLATION occurred at PC=0x6D2AB850
        Function=[Unknown.]
        Library=D:\jdk14101\jre\bin\jsound.dll

        NOTE: We are unable to locate the function name symbol for the error
              just occurred. Please refer to release documentation for possible
              reason and solutions.

        When I run the following test program on 1.4.2beta, I get crashes - possibly related to this bug:

        <test program moved to bug 4835956>

        ###@###.### 2003-03-24
        Removed the test program. It did produce a crash, but at Sequencer.open() and not at close(). So I filed a new bug for it: 4835956, which is fixed and integrated for mantis-beta.

        This bug here - crash at Sequencer.close() - remains not reproducible by me. I may have to install the WTK TCK to find out more.
