This bug is filed only for tracking purposes, the fix has already been
integrated in jdk1.2, so feel free to close it as such.;

The excerpt from the spec for java.awt.event.KeyEvent class:
"
...
public static final int VK_UNDEFINED
  KEY_TYPED events do not have a defined keyCode.
...
public static final char CHAR_UNDEFINED
      KEY_PRESSED and KEY_RELEASED events which do
      not map to a valid Unicode character do not
      have a defined keyChar.
....
".
So, it is possible to create a KeyEvent object via
calling to
KeyEvent(some_correct_component,
         KeyEvent.KEY_TYPED,
         some_correct_long,
         some_correct_int, KeyEvent.VK_UNDEFINED)
constructor.

Nevertheless, this constructor will throw IllegalArgumentException
_always_ in jdk 1.1.8. Below the piece from jdk 1.1.8 source for
java.awt.event.KeyEvent:
"
...
    public static final int VK_UNDEFINED = 0x0;
...
    public static final char CHAR_UNDEFINED = 0x0;
...
    public KeyEvent(Component source, int id, long when, int modifiers,
                    int keyCode, char keyChar) {
        super(source, id, when, modifiers);

        if (id == KEY_TYPED && keyChar == CHAR_UNDEFINED) {
            throw new IllegalArgumentException("invalid keyChar");
        }
        ...
    }
...
    public KeyEvent(Component source, int id, long when, int modifiers,
                    int keyCode) {
        this(source, id, when, modifiers, keyCode, (char)keyCode);
        // (char)keyCode equals to VK_UNDEFINED equals to 0x0
    }
"
