FULL PRODUCT VERSION :
java version "1.4.1"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.1-b21)
Java HotSpot(TM) Client VM (build 1.4.1-b21, mixed mode)


FULL OPERATING SYSTEM VERSION :

Microsoft Windows 2000 [Version 5.00.2195]

EXTRA RELEVANT SYSTEM CONFIGURATION :
This was tested both with and without "Hide keyboard
navigation until I use the Alt key" checked.

A DESCRIPTION OF THE PROBLEM :
If a submenu has the same mnemonic as an item in that
submenu, then pressing that letter to activate the submenu
will activate the menu item too. This makes it impossible
to browse that submenu using mnemonics.

REGRESSION. Last worked in version 1.4

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Compile the following program and run it.
2. Press Alt-A.
3. Press B.

EXPECTED VERSUS ACTUAL BEHAVIOR :
Expected: When Alt-A is pressed, menu A opens. When B is
pressed, submenu B1 opens.

Actual: When Alt-A is pressed, menu A opens. When B is
pressed, menu item B2 (under B1) immediately fires. This
is demonstrated by the menus closing and a line being
printed to the console.

REPRODUCIBILITY :
This bug can be reproduced always.
