Okay I figured it out.

For any one who might be interested in the future, use an inherited java.awt.Component method to get g:

Graphics g = cc.getGraphics();
cc.update(g);

Maybe your Event Dispatch Thread is stuck? If that is the case, *nothing*
gets drawn, so you should be able to verify this theory by starting the
"Monitor Memory..." command first; it will not update either during the
time the Event Dispatch Thread is blocked.

Ciao,
