While running my application in a RedHat virtual machine I get an exception when starting with JOGL2rc10 that I don't get with JOGL1.1.1.

In both circumstances I get a warning:
Xlib:  extension "NV-GLX" missing on display ":0.0".

I get the same warning if I run glxgears and it's running a MESA driver (glxgears -info)
Xlib:  extension "NV-GLX" missing on display ":0.0".
GL_MAX_VIEWPORT_DIMS=4096/4096
GL_RENDERER   = Mesa GLX Indirect
GL_VERSION    = 1.2 (1.5 Mesa 6.2.1)
GL_VENDOR     = Mesa project: www.mesa3d.org


I have just noticed though the GL_VERSION above is GL1.2 but my application is request a GL2 profile.

If this is the issue, i don't think it should segfault the VM though.
