I've seen this "GL_VERSION is NULL" bug too. On Windows 7 64-bit, the last autobuild version that doesn't have this bug is autobuild b244 -- every version after that fails. I'm going to submit a bug report for this soon, I was just trying to debug it more first.

In the meantime, I'm just running b244, which seems to work OK. The TestGearsGLJPanelAWT test works on this build, so your GLJPanel stuff may work on it too. You might take a look at it, the path is jogl\src\junit\com\jogamp\test\junit\jogl\demos\gl2\gears\TestGearsGLJPanelAWT.java.
