> JaninoRelMetadataProvider uses IClassBodyEvaluator to compile generated code.  The generated classes can not be debugged in interactively using Idea using the method referenced by http://janino-compiler.github.io/janino/ because generated code only contains classBody. 
> If using ISimpleCompiler to compile complete compile unit instead of classBody, we could step into the code.
