Yes. This is something that could be done with JExtract I think.

Lot of opengl features rely on extensions and you do not really know in advance which extensions are available on your clients' computers. There is also GLSL which can also be versionned separately from OpenGL. Sven Gothel has done a great work in JOGL to improve this. Yet, it remains a bit of headache to have a consistent multiplatform experience in such an heterogeneous world!

Java3D was dropped in 2004 from JDK and JOGL was given to the community. Does someone know what the reasons were? I fear writing something similar to what was done 20 years ago would fail the same way :)

At the time, JNI was seen by some as kind of defensive wall for Java. Now, not nearly so much. In fact, now Panama’s much more welcoming stance to native code is an important side to Java. Panama has been inspired, in part, by some of those old projects from 20 years ago.
