      Description

      FULL PRODUCT VERSION :
      java version "1.7.0_04-ea"
      Java(TM) SE Runtime Environment (build 1.7.0_04-ea-b19)
      Java HotSpot(TM) 64-Bit Server VM (build 23.0-b20, mixed mode)

      ADDITIONAL OS VERSION INFORMATION :
      Mac OS X 10.7.3

      A DESCRIPTION OF THE PROBLEM :
      When the ScreenMenuBar is activated using System.setProperty("apple.laf.useScreenMenuBar", "true"); and the registered Accelerator Key for a JMenuItem is pressed, the ActionListener is called twice.


      REGRESSION. Last worked in version 6u31

      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      Activate the usage of the Screen Menu Bar
      System.setProperty("apple.laf.useScreenMenuBar", "true");

      Create a JFrame with a JMenuBar, JMenu and a JMenuItem and register a hotkey to the JMenuItem using setAccelerator and add an ActionListener.

      Start the test application and press the Hotkey.

      EXPECTED VERSUS ACTUAL BEHAVIOR :
      EXPECTED -
      Having the ActionListener called once per pressed hotkey.
      ACTUAL -
      The ActionListener its called twice.

      REPRODUCIBILITY :
      This bug can be reproduced always.
