Description Sebastien Schneider 2011-12-02 11:39:04 CET 
When I call getMouseListeners or getWindowListeners or getKeyListeners ... on a NEWT GLWindow I get a java ClassCastException that says that a Java Object array cannot be cast to a NEWT Listener array:
[Ljava.lang.Object; cannot be cast to [Lcom.jogamp.newt.event.MouseListener; in the case of the GLWindow.getMouseListeners()

Hi

For example, getWindowListeners() should not use toArray() because it returns Object[] instead of WindowListener[].

This method:
public WindowListener[] getWindowListeners() {
    return (WindowListener[]) windowListeners.toArray();
}

should be replaced by this one:
public WindowListener[] getWindowListeners() {
    return windowListeners.toArray(new WindowListener[windowListeners.size]);
}

There is the same bug with getKeyListeners(). If you don't want to use <T> T[] toArray(T[] a), just use a simple loop. Best regards.
