      Description



      Name: jk109818 Date: 02/14/2002


      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.
