This is probably a bug in NVidia's drivers that Sven found and
worked around by avoiding calls to glXGetCurrentContext().
Unfortunately the workaround is still only in the source tree at
sourceforge and binaries haven't been released with the fix.
Sven, could you build what you've got and call it 2.8.3?

You'll need to check out the current sources with CVS.

You should run with the debug version of the library under the
debugger to try to isolate the crash. OpenGL programming errors
can result in application crashes regardless of the programming
language used. You can also call GLContext.checkGL() (not sure of
the exact name) from various points in your application to try to
isolate where an OpenGL error may have been raised.

That would be really good, if you could do it in the next few days. If not, I 
could try to build it from source. What is the version at sourceforge that 
contains the fix? I can only find the elderly  GL4Java-Source 
rel-2-8-0-8-prerelease from November 5, 2001. Or should I check out from cvs?

I tried the cvs version but I still get this error.

Btw building the source was a pain. It builds the whole stuff like 20 times. 
I cant see a reason why. And it failed to build the shared libraries without 
telling me so. I had to copy the .class files from a previous build try from 
HOME_LIB_DIR to ./gl4java. Somehow it didnt put them there, but later it 
expected them to be there. 

Any other suggestions what I could try for this error? If not, I'll have to 
stay with Mesa and software rendering for this project, and not use gl4java 
in the future.

[gl4java-usergroup] Weird size texture loading

[Drake W. <dr...@er...>]

I am trying to load some VRML files that already exist.  But the image sizes
that come with it are all weird size (123x843 or whatever)

I can't load them unless they are the same size horizontally and vertically.
Is this normal?  I was expecting that I could either
load any size or only load 64x64, 128x128, 256x256, 512x512... ect....

Or should I open the pngTextureLoader and adding the support?

Or has anyone created a Graphic Texture Loader?  (anythign inside a standard
Graphic can be loaded)... So you create a graphic of the size you want and
paste the image.  This might be a cool addition so that you could create a
texture using AWT and standard components.

thanks
