JVM hang with Swing and macOS

[Martin Pernollet]

Yep have been away from java and GL for some time hence answering oldest message first, but don't worry I will answer :)

That is awesome if you had MESA working on macOS. I am curious how you solved the issue with library loading.

If you bumped PanamaGL from Java 19 to 20 that is awesome. I was about to start this soon but I'd be glad to rather review your work through a PR on the gitlab projects. The more people able to commit to this code base, the best for this project.

I'll answer more in depth to your recent message.

Thank you a lot.
