When we inputted space key or enter(return) key in JTextField, the differences of action of KeyEvent happened between on Solaris and Windows NT.
We found the differences of action of KeyEvent in following four cases.

- case1 : when we input <space> in JTextField without mode of inputting 
          japanese
- case2 : when we input <space> in JTextField with mode of inputting japanese
          (as no translation)
- case3 : when we input <space> in JTextField with mode of inputting japanese
	  (as translation)
- case4 : when we input <enter> (Return key) in JTextField with mode of
	  inputting japanese (as translation)

The detail of result is below (o : KeyEvent appears , x : KeyEvent didn't appear ),

- case1 :
	                 Solaris Wnn6  ATOK8 cs00  WinNT(MS-IME97,ATOK11)
keyPressed              	o     	 o     o     o
keyTyped                	o     	 o     o     x
keyReleased             	o     	 o     o     o

- case2 :

               		 Solaris Wnn6  ATOK8 cs00  WinNT(MS-IME97,ATOK11)
keyPressed              	o     	 x     x     x
keyTyped                	o     	 x     x     x
keyReleased             	o     	 x     x     o

- case3 : 

               		 Solaris Wnn6  ATOK8 cs00  WinNT(MS-IME97,ATOK11)
keyPressed              	x     	 x     x     x
keyTyped                	x     	 x     x     x
keyReleased             	x      	 x     x     o

- case4 :

               		 Solaris Wnn6  ATOK8 cs00  WinNT(MS-IME97,ATOK11)
keyPressed              	x     	 x     o     x
keyTyped                	x     	 x     o     x
keyReleased             	x     	 x     o     o


These results may be dependent of each IME, but we think that java must be
independent of platform. So, especially, we hope next points.
1. In case1, keyTyped event happens on windows NT.
2. In case2, case3 and case4 , keyReleased event don't happen on Windows NT.

Then these results can be reproduced by following IMFTest.java .
