Thanks - using JOGL 2.0-b3-20101124 gives correct rendering using the default GLProfile for my system.
I see the GLCapabilities derived from this profile now defaults to requesting a 16-bit depth buffer (as observed by GLCapabilities.getDepthBits()). For completeness/spam :), output below.
Perhaps interestingly, it seems the demo can now use a 24-bit depth buffer if this is requested. See second output below.
Thanks for everyone's comments and assistance since I joined the thread - hope it means the original problem has been solved too!
