i tested /javax/sound/sampled/Clip/ClipFlushCrash from Regression suite on RHEL5_64, it got in deadlock at line:
at1.terminate();
at2.terminate();
at3.terminate();//after it it hanged
at4.terminate();
at4.terminate() call public synchronized void terminate()
but at1,at2,at3 went out before at4.terminate(), so it went in deadlock (with what thread i donot understand) and so it has error(timeout)
