[antlr-interest] How to extend the CommonTree without getting a classcastexcpetion in the generated code?

[Marwan Ajraoui]

I think that altering code generation so catch-clauses get replace
with the action specified is the best aproach in my case:

@rulecatch {
catch (RecognitionException e) {
    ...
    throw e;
}
}

Cheers,
