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

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

The GLVersion JOGL dumps is explained in detail here:

The OpenGL inclusion criteria and why OpenGL 3.0 is 'only' GL2 
is described here:

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.
