Hello, Could you review the fix for the issue: bug: http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=7161766 webrev: http://cr.openjdk.java.net/~alexsch/7161766/webrev.00/
The system can disallow to overlap the task bar for popup-menu even the SecurityManager is not set. There are systems which default security manager created by new SecurityManager() allows to overlap the task bar.
So what it is possible to check is setting the security manager that does not allow to be always on top and checking that the popup-menu does not overlap the task bar in this case.
The fix sets a SecurityManager that throws the SecurityException for the setWindowAlwaysOnTop property and checks that the popup-menu does not ovelap the task bar.
Thanks, Alexandr.
