getKeyCode(), getKeyChar() returns incorrect value at KEY_PRESSED event.

Run the attached program and operate.
When pressed some keys, getKeyCode() and getKeyChar() returns incorrect value.

- Windows

    in case of '-', '\(back slash)' :

      Result : keyCode=0 & keyChar=' '
      --------------------------------------------------------------------------------
      java.awt.event.KeyEvent[KEY_PRESSED,keyCode=0,keyChar=' '] on textfield0:
             Unknown keyCode: 0x0/
      java.awt.event.KeyEvent[KEY_TYPED,keyCode=0,keyChar='-'] on textfield0: -
      java.awt.event.KeyEvent[KEY_RELEASED,keyCode=0,keyChar=' '] on textfield0
      --------------------------------------------------------------------------------
      
    in case of '\(yen sign)', '[', ']', ';', ':', '/', '.', ',' :

      Result : keyChar=' '
      --------------------------------------------------------------------------------
      java.awt.event.KeyEvent[KEY_PRESSED,keyCode=92,keyChar=' '] on textfield0: \/
      java.awt.event.KeyEvent[KEY_TYPED,keyCode=0,keyChar='\'] on textfield0: -
      java.awt.event.KeyEvent[KEY_RELEASED,keyCode=92,keyChar=' '] on textfield0
      --------------------------------------------------------------------------------

- Solaris

    in case of '-' : keyCode=0

      Result:
      --------------------------------------------------------------------------------
      java.awt.event.KeyEvent[KEY_PRESSED,keyCode=0,keyChar='-'] on textfield0:
             Unknown keyCode: 0x0/ -
      java.awt.event.KeyEvent[KEY_TYPED,keyCode=0,keyChar='-'] on textfield0: -
      java.awt.event.KeyEvent[KEY_RELEASED,keyCode=0,keyChar='-'] on textfield0
      --------------------------------------------------------------------------------

When these operate with shift key, result are the same.

<reference>
    JDK1.2beta3 : getKeyCode() returns incorrect value, but getKeyChar() returns
                  correct value.
    JDK1.1.6 : all of keys retruns available KeyCode and correct KeyChar.
                  This is inconvenient for the application that treats also function key,
                  because the application has no means to know that next KEY_TYPED
                  has charcode, when the application received KEY_PRESSED.
