The bug report is great, thank you.
[Don't know why you renamed the test.log and test_dbg.log files though :]

I assume the confusion is that instead of using the Nvidia GT540M GPU,
you have used the Intel build-in GPU, see below.

I don't know how you switch over to the powerful GPU .. well.

The Intel driver you use is capable of OpenGL 3.0 only:
  GL_VENDOR     Intel
  GL_VERSION    3.0.0 - Build 8.15.10.2342

JOGL maps OpenGL 3.0 to GL2:
  GL2 true[3.0 (compatibility profile, any, new)]

The GLVersion JOGL dumps is explained in detail here:
<http://jogamp.org/deployment/jogamp-next/javadoc/jogl/javadoc/javax/media/opengl/GLContext.html#getGLVersion%28%29>

The OpenGL inclusion criteria and why OpenGL 3.0 is 'only' GL2
is described here:
<http://jogamp.org/deployment/jogamp-next/javadoc/jogl/javadoc/overview-summary.html#GLAPIInclusionCriteria>

In short, the GL3 Profile 'world' actually start with OpenGL 3.1,
see OpenGL 3.0 as premature release which didn't introduce the new native
ARB Context semantics etc.

So, it's not a bug - it's a feature.
