<Swing Dev> [9] Review request for 8072900: Mouse events are captured by the wrong menu in OS X

[Anton Nashatyrev]

Hello,
     could you please review the following fix:

<http://cr.openjdk.java.net/%7Eanashaty/8072900/9/webrev.00/>
bug: https://bugs.openjdk.java.net/browse/JDK-8072900

The problem: On MacOS if there are two frames with menu, the first is 
opened and the mouse moved over the second it causes the second menu to 
be opened.

The reason: the AquaMenuUI creates its own MouseHandler and the logic of 
mouseEnter() has not been completely ported from the BasicMenuUI.

Thanks!
Anton.
