EVALUATION An execution sequence look like: Applet-thread EDT \| \| A1) press-release E1) robotSema.notify() A2) robotSema.wait() E2) invokeLater on {waitTillShown(d); d.toFront()} A3) press-release E3) dialog.show() A4) pressSema.wait() E4) pressSema.notify() The logic here is as follows: robot triggers action event on Button and then blocks AppletMain thread with wait(). That action event notifies the robotSemaphore and then posts some code with invokeLater() and then shows the dialog. If robotSemaphore notified fast enough then the robot bursts press-release even earlier the dialog becomes visible. So far all keyevents has come to the button instead of just appeared dialog. I don't see an easy way to make things going right in 100% cases but I'd move robotSema.notify() in between E2) and E3). This wouldn't change the test's logic but increases the chance of passing the test in my environment.

EVALUATION In jdk7 (latest build) the test works fine on Windows 7. Seems like XP-specific issue.

EVALUATION Reproduced with jdk6 and jdk7. Looks like a thread race as I had to try it several times to get the failure.
