DefaultGraphicsConfiguration cast exception

One of my clients got the following exception when trying to run my Ardor3D software in his Mac laptop:

Hi

We need a small test case to reproduce this bug. I don't understand why a DefaultGraphicsConfiguration is returned by chooseGraphicsConfiguration in this case.

Please be more precise about the version of Mac and the JVM.

I got myself a test Mac to test it but I get a different exception on this one.

Java Web Start 1.6.0_37
MacBook1,1
Intel GMA 950:

  Chipset Model: GMA 950
  Type: GPU
  Bus: Built-In
  VRAM (Total): 64 MB of Shared System Memory
  Vendor: Intel (0x8086)
  Device ID: 0x27a2
  Revision ID: 0x0003

Here is the exception I get:

Can you reproduce it with an example provided with Ardor3D? Which version of Mac OS X do you use? 10.7?

Yes, I can reproduce it with JoglAwtExample.
Mac OS X version is 10.6.8

Here is the exception of that JoglAwtExample generates:

Thank you runiter. Maybe you will have to fill a bug report.

Where can I file a bug report?
