The method ruleeState() is undefined for the type InternalRpcIDLParser4 [message #1151388]

I got an error in my xtext compilation:
The code for the static initializer is exceeding the 65535 bytes limit InternalRpcIDLParser.java /org.xtext.rpcIDL.ui/src-gen/org/xtext/ui/contentassist/antlr/internal line 23 Java Problem

I searched online regarding the solution and I found that I can fix it by adding these in XtextAntlrGeneratorFragment and XtextAntlrUIGeneratorFragment:

options = {
                classSplitting=true
                fieldsPerClass="200"
                methodsPerClass="100"
                  }

This got rid of the 65535 limit error but introduces a lot of other bugs.

This is the error:
The method ruleeState() is undefined for the type InternalRpcIDLParser4 InternalRpcIDLParser.java /org.xtext.rpcIDL/src-gen/org/xtext/parser/antlr/internal line 24785 Java Problem

eState is an enum in my grammar file. All the errors are about an undefined method rule of all my enum in the grammar file.

Does someone have an idea on how to fix this?

Update:

I tweak the values for fieldsPerClass and methodsPerClass, and set it to 200 and 500 respectively, which made the errors go away.
But the generator is not able to do the sorting algorithm correctly. I am using the
java.util.Comparator.

Question:
How will I compute for the appropriate values to be set in fieldsPerClass and methodsPerClass?

Aside from adding these options in XtextAntlrGeneratorFragment and XtextAntlrUIGeneratorFragment, are there other settings I need to do to make this work correctly?

I'm hitting the 65535 bytes limit, too. And for me specifying the recommended options of classSplitting etc. also makes the resulting parser uncompilable (methods are called from scopes where they are not available).

Is there anything else I need to specify?

For now, I found that using the default numbers (rather then the recommended 200 e.g.) works around the problem but this feels fragile to me...

thanks
Stephan
