FULL PRODUCT VERSION :
java version "1.4.0"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.0-b92)
Java HotSpot(TM) Client VM (build 1.4.0-b92, mixed mode)

FULL OPERATING SYSTEM VERSION :
Microsoft Windows XP [Version 5.1.2600]

ADDITIONAL OPERATING SYSTEMS :
Korean Version


A DESCRIPTION OF THE PROBLEM :
KeyEvent.VK_INPUT_METHOD_ON_OFF should on/off Korean Input
Method.
In JVM on Korean OS, KeyEvent.VK_INPUT_METHOD_ON_OFF is
interpreted as on/off Korean <-> Chinese Character.
But, It's not a we want.

An article in Bug parade
(http://developer.java.sun.com/developer/bugParade/bugs/4267564.html)
described that Nihongo Key in Japanese keyboard and Hanja
key in Korean keyboard have the same function, but it's not
a truth.
Actually, Nihongo Key in Japanese keyboard and Hangul key in
Korean keyboard are the same.

The problem of this bug is that Korean programmer can't make
a Automated UI testing program using java.awt.Robot.
Robot's keyPress(), keyRelease() methods are good. But, due
to the wrong definition of KeyEvent.VK_INPUT_METHOD_ON_OFF,
Robot can't generate Korean Charanter.






STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Write program using java.awt.Robot
2. use "keyPress(KeyEvent.VK_INPUT_METHOD_ON_OFF)"
 and "keyRelease(KeyEvent.VK_INPUT_METHOD_ON_OFF)"
3. use "keyPress(KEYEvent.VK_R)" and
"keyRelease(KEYEvent.VK_K)" (or use "VK_K" and "VK_F" in
3_beolsik_keyboard)

EXPECTED VERSUS ACTUAL BEHAVIOR :
java.awt.Robot should on/off Korean Input Method.

This bug can be reproduced always.
