Regression test java/awt/Focus/TemporaryLostComponentDeadlock/TemporaryLostComponentDeadlock.html
from the Regression-test test suite for JDK1.4.2-b28 fails on JDK1.4.1, JDK1.4.2, JDK1.5.0.

The test passes intermittently on JDK1.4.2, JDK1.5.0.

The test fails because of race conditions: the thread that calls frame1.dispose() and
frame1.notify exits before the main thread enters frame1.wait().

Here is an excerpt from TemporaryLostComponentDeadlock.java:

        new Thread() {
            public void run() {

/* when I added the following line the test passed
                try{ Thread.sleep(1000); } catch( InterruptedException ie) {}
*/
                synchronized(frame1) {
                    frame1.dispose();
                    synchronized(frame1) {
                        frame1.notify();
                    }
                }
            }
        }.start();
        try {
            synchronized(frame1) {
                frame1.wait();
            }
        } catch( InterruptedException ie) {
        }
        Sysout.println("Test PASSED");

I modified the test source as shown above and the test started to pass everytime.
