[cp-patches] FYI: BasicMenuUI fixlet

[Anthony Balkissoon]

This patch makes our JMenu usage more compatible with the reference
implementation.  Oddly enough, calls to JMenu.setSelected will allow
more than one menu in a menubar to be selected, so I wrote popupVisible
to make clear the criteria for selecting a menu due to a mouse entered
event.

Removing the check for !menu.isArmed is so that if a menu is selected
but doesn't have its popup menu showing, and then receives a valid mouse
entered event (while another menu is open), it will show its popup menu.

Patch attached.

* javax/swing/plaf/basic/BasicMenuUI.java:
(MouseHandler.popupVisible): new method.
(MouseHandler.mouseEntered): Removed check for menu being armed to
comply with reference implementation.  Calls popupVisible to check
for menus with their popup menu visible
