1.15.2 server crashes on load with this mod

I wasn't sure where to report this exactly but I can reproduce it using fabric-language-scala so I'll post it here and hopefully this will end up in the right place.
Starting a 1.15.2 server with only fabric-language-scala 0.3.1.11 and no other mods causes the server to crash. As best as I can tell there's an issue with the wrong log4j being present at runtime.
I tried building fabric-language-scala with updated yarn and loader dependencies
yarn_mappings=1.15.2+build.15
loader_version=0.7.10+build.191but that had the same issue.

Looks like the two logger classes get loaded by two different class loaders. would be a bit difficult to debug.
I guess not using the logger is one way to fix it. I apologize if it's bad etiquette to close this.
