KeyEvent.setSource() takes an Object as its argument. Thus a KeyEvent's source
is not guaranteed to be a Component and the cast in
ComponentEvent.getComponent() may fail!

Is that original line of code
     "return (source instanceof Component) ? (Component)source : null;"
really so expensive that it's worth all that trouble to avoid it? Remember that
ComponentEvent is not final and the source field (of type Object) is protected,
not private!
