javax.sound.sampled
Classic VM (build 1.3.1-p7-root-021014-00:03, green threads, nojit)

1.4.0-internal-root_08_dec_2002_16_37, mixed mode)
JavaSoundDemo.jar
Hardware doesn't make sence.
>Description:
        A Deadlock happens on the sound capturing (captureLine.read(...)) after a 
second open of the Capture Line.
        It looks like a DeadLock in a native part of the java sound library.
>How-To-Repeat:
        - start the JavaSoundDemo.jar
        - select the "Capture/Payback" tab
        - press the "Record" button, recording will start
        - press the "Stop" button, recording will stop
        - press the "Record" button, recording WILL NOT start        
>Fix:
        Hopefully a "restart of the sound system" before opening a CaptureLine will 
help (if all corresponded threads will be killed).
        But the implementation classes are not public.
