        I did my tests on Solaris. In a sample test program, I have a loop
        that creates a DataLine, writes some data to it, then closes it after
        finish writing the data. After running the program for a while, it either
        crashes or hang the VM.

        With JDK 1.2.2, I was able to crash the VM sometimes after looping for
        50 times. Other times, it may take longer -- after looping for 6000 times
        in 30 minutes. The stack trace is included in the Comments section.

        With JDK 1.1.*, it may hang the VM after a while.
