Hi Sergey,
Maybe the robot mouse events are not getting enough time to be processed
which is why the toolkit shutdown is not able to happen as those are
still in the event queue. Adding waitForIdle() in the test allows those
robot events to be processed and then toolkit thread gets chance to get
disposed and system shutdown takes place ok.
Regards
Prasanta

Hi, Prasanta.
I think that the suspicious place in the stack is below, it tries to
execute hooks during system shutdown and hangs.
The hook which hangs is "ToolkitShutdown #18 daemon" from the WToolkit
class. I guess that the code which hangs is a loop in the:
Java_sun_awt_windows_WToolkit_shutdown:
while (!tk.IsDisposed()) {
Sleep(100);
}
So it does not look like a test bug.
