I have done that on GLCanvas:

but the problem will still be there, you will just get an error message "Error: Couldn't fetch AWTGraphicsConfiguration" instead of the ClassCastException. The problem is that a DefaultGraphicsConfiguration is returned instead of the one for AWT.

The other bug with NewtCanvasAWT will have to be fixed too.

@Sven, if you have an idea, let me know.
