FULL PRODUCT VERSION :
java version " 1.7.0_21 "
Java(TM) SE Runtime Environment (build 1.7.0_21-b11)
Java HotSpot(TM) Client VM (build 23.21-b01, mixed mode, sharing)

ADDITIONAL OS VERSION INFORMATION :
Microsoft Windows [Version 6.1.7601]


EXTRA RELEVANT SYSTEM CONFIGURATION :
Microsoft Office IME 2010

A DESCRIPTION OF THE PROBLEM :
Component#enableInputMethods(false) does not disable IME with JRE7.
There is no problem with JRE6. So, it is a regression issue between JRE7 and JRE6.

Javadoc:
http://docs.oracle.com/javase/7/docs/api/java/awt/Component.html#enableInputMethods(boolean)


REGRESSION. Last worked in version 6u45

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1) Launch KeyListenerTest as Java Applet with JRE7
2) Press VK_HALF_WIDTH or VK_FULL_WIDTH key


EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
IME not enabled.
KeyListenerTest as Java Applet can catch key press events such as VK_HALF_WIDTH or VK_FULL_WIDTH with KeyListener.

ACTUAL -
IME enabled.
Some key press events such as VK_HALF_WIDTH or VK_FULL_WIDTH are consumed by IME.
Therefore, it is unable to catch such key events with KeyListener.


REPRODUCIBILITY :
This bug can be reproduced always.
