When using JOGL with an external context (the context has an on screen
drawable provided by SWT) glTexImage2D fails. The relevant part of the stack
backtrace is included.
javax.media.opengl.GLException: Context not current
Please note that glTexImage2D is indeed called on the correct (and cureent)
context. Because of problems with generating the GLImpl code I cannot have a
look at how you've attempted to optimize texture loading, although the intent
is obvious from the stack backtrace.
To me this looks a lot like JOGL fails to catch that exception and therefore
is unable to fall back to a plain call of glTexImage2D. If this is what
happens, then this behaviour is clearly a bug.

I forgot to mention that this happens with the nightly build from 2006-02-22.

It looks like there has been a bug basically forever in the X11ExternalGLContext
code where the mostRecentDisplay was never set, causing failure of extension
queries. I find it hard to believe that this could have been broken for this
long, but it's pretty clear a bug was there. It's been fixed in the JOGL tree
and will show up in the nightly build of 2/23. Please retest with that build or
later and verify the fix. Please also double-check that the application is
calling makeCurrent()/release() on the external GLContext, which is required
even though it will not change the actual underlying OpenGL context. FYI, this
had nothing to do with texturing specifically.

OK, there are no more exceptions with the new version, so it appears to be
