Unable to Launch modded Minecraft 1.12.2

[shanoaice]

I came across this Java SE 8 implementation in .NET and wondered whether it is possible to use this to play Minecraft. Original 1.12.2 without any modding launches fine, but when I tried to add Forge and a few mods, game would refuse to launch. This is the startup log.

When I tried it on an even larger modpack, it throws a stack overflow. Logs.

So while kinda neat, this probably isn't something I'm going to have the time to take a deep look at. If you have time though, a simpler reproduction would be nice.

The stack overflow seems to be a recursive loop in parsing some annotation, since its passing through getDeclaredAnnotationsImpl.
