FULL PRODUCT VERSION :
java version "1.7.0_02"
Java(TM) SE Runtime Environment (build 1.7.0_02-b13)
Java HotSpot(TM) Client VM (build 22.0-b10, mixed mode, sharing)


ADDITIONAL OS VERSION INFORMATION :
Microsoft Windows [Version 6.1.7601]

A DESCRIPTION OF THE PROBLEM :
If a Label control is configured with a mnemonic, the Alt/Key combination does not move focus to the text field configured in the "labelFor" property.
Instead the focus goes to the first menu.

REGRESSION. Last worked in version 6u31

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1) Run the attached sample code.
2) Click on the “First name” text field.
3) Press Alt/L to move the focus to the “Last name” text field.


EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Focus should move to “Last name” text field instead of moving to menu “FirstMenu”.

ACTUAL -
Focus is not moved to “Last name” text field. Instead the focus is moved to menu “FirstMenu”.


REPRODUCIBILITY :
This bug can be reproduced always.
