How to initialize a TruffleLanguage was Getting delegate of an EngineTruffleObject

[Vlad Vergu]

Hi,

I’m running into a different issue now, trying to update to Truffle 0.25.

When I create a RootNode in the implementation of TruffleLanguage#parse(ParsingRequest) an IllegalArgumentException is thrown with message ‘Truffle language instance is not initialized’. The language class has a @TruffleLanguage.Registration. What should i be doing to initialize the language? Thanks.


Best regards,
Vlad
