System: Windows NT4.0 Running under Japanese locale, With Japanes 106 Keyboard

To reporduce:

1. Compile the attached program PanelTest and run it
2. Type Shift+2, instead of getting character " (double quote) gets character @
3. Type Shift+9  instead of getting character ) (close brace) gets ( open braces

Layout follows keys defined US-101 ASCII Keyboard layout

The attached two java files listen for keyboard events and print the 
revceived key sequences. The difference is PanelTest is with 1.0 event
model and CanvasEditor with 1.1 model. CanvasEditor works with Japanese
keyboard with JDK1.1.1 where as PanelTest doesn't work with Japanese keyboard.
