The language class has a @TruffleLanguage.Registration. What should i be doing to initialize the language? Thanks.

Sounds familiar.
Don’t remember the exact details thought.

I presume, you reached parse() via an eval() call on the polyglot engine?

Make sure you don’t have the singleton instance of the language around anymore, I think that interfered with initialization in my case.
And make sure that the instance of your language is the correct one.

Best regards
