DESCRIPTION:
Windows' preedit window should not display on active component.
Because Java handle preedit string by itself.
But when I tried following operation, Windows' preedit window is displayed.
Test instruction is as follows:
1. Run attached test program (JTextInputTest.java)
2. Check Weekday list window has focus, if not, click Weekday list window
3. Turn Japanese IME, type "nichi" (Floating preedit window is displayed)
4. Move window focus to JTextArea window
5. Turn Japanese IME, type "getsu" and press Space key twice.
   At this moment, unexpected preedit window is displayed on left-top window.
J2SE 64bit version also has this problem but situation is not same.
