Regression-test javax/sound/sampled/Clip/ClipFlushCrash.java test fails with timeout
using JDK1.5.0-b29.

It seems like the test fails because of synchronization problems:

Here is the test source fragment:

--------- ClipFlushCrash.java ---------
...
     68            AT at4 = new AT(clip, "open/close thread", 600) {
     69            public synchronized void doAction() throws Exception {
     70                log("close");
     71                clip.close();
     72                wait(50);
     73                if (!terminated) {
     74                    log("open");
     75                    bais.reset();
     76                    clip.open(new AudioInputStream(bais, format, frameCount));
     77                }
     78            }
     79            };
     80
     81            out(" clip.start");
     82            clip.start();
     83            out(" for 10 seconds, call start/stop, setFramePosition, and flush from other threads");
     84            at1.start();
     85            at2.start();
     86            at3.start();
     87            at4.start();
     88            try {
     89                Thread.sleep(10000);
     90            } catch (InterruptedException ie) {}
     91            out(" finished.");
     92            at1.terminate();
     93            at2.terminate();
     94            at3.terminate();
     95            at4.terminate();
     96            out(" clip.close()");
     97            clip.close();
     98            success++;
...
---------------------------------------

Problem is that at4 can be closed when the main thread tries to terminate it, so the test hangs
at the line 95 and never finishes.

The test stable passes if I increase waiting time at the line 72:
...
     72                wait(10000);
...
