I am trying to embed a GLJPanel in another panel in my application. It works fine when i try to place it in a frame, but not when I try to place it embedded in anything else, like a panel. I get this exception:

Exception in thread "AWT-EventQueue-0" java.lang.RuntimeException: Nativewindow X11 Error: Display 0x7fdce813e280, Code 0x3

Anyone have any ideas?
