A DESCRIPTION OF THE PROBLEM :
A JPopupMenu which is opened from a JWindow is cancelled by Swing when clicking on a JMenuItem inside the JPopupMenu. The JMenuItem does not receive an ActionEvent.

The problem occurs on Mac OS X only and works fine on Windows and Linux.


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Start the sample application (see below).
2. Within the window click on the button "ShowPopup".
3. Within the popup menu click on "ClickMe".
4. The ActionListener of button "ClickMe" does not fire.


EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The ActionListener of button "ClickMe" should fire and the sample application should be closed.

ACTUAL -
The popup menu was closed after step 3 and nothing else happened.


REPRODUCIBILITY :
This bug can be reproduced always.

CUSTOMER SUBMITTED WORKAROUND :
The sample works when the parent window of the popup menu is a "JFrame" instead of a "JWindow".
