Release CheerpJ JNI headers

[MausKaffee34767-2]

Release the CheerpJ JNI headers:

#27 (comment):

We could experimentally build LWJGL3 by using some unsound hacks, but these hacks are too unstable to be published. The library uses some JNI features which are not currently supported properly by our JNI implementation for CheerpJ.

Our plan is eventually release our JNI headers and library and allow CheerpJ users to compile their own libraries to WebAssembly, but this is something that we cannot prioritize at this time.

I'll keep this issue open as support for LWJGL3 is something that we want to eventually provide

#8 (comment):

Although we have internally achieved up to 1.16.5, there is further work required that we cannot schedule at this time.

Moving a few version further would not truly make a difference in the value of this demo, so that is also not a priority.

1.16.5 implies LWJGL3

Releasing the JNI headers would allow many native libraries to be compiled to wasm a natively used with cheerpj without having to port them to javascript.

It's true that we have achieved running Minecraft 1.16.5 on top of LWJGL3, but this is still using the unsound hacks that we mentioned.

We do plan to release our JNI implementation and allow third parties to build JNI modules for CheerpJ, but that is not an immediate priority. I'll keep this issue open so that you'll be notified when this eventually happens.

Thanks for the fast response. I was not even asking for these unsound hacks, I just asked for the headers. I understand that for a company like Leaningteach there are other immediate priorites (see other products like cheerp) and am looking forward to the release of the JNI headers.
