I replaced JoglAwtCanvas with JoglNewtAwtCanvas in ardor3d example and it worked but in my program it gives the following exception. Any ideas what could be causing it? As far as I can tell my program is very similar than the ardor3d example.

Edit: I noticed that I can get the above exception if I remove frame.pack() from the example. Adding frame.pack to my code didn't help though, probably because I have a more complex swing UI. So question is what does frame.pack() has to do with rendering canvas. Here is the exception:
