[antlr-interest] Big grammar => static initializer/method size is exceeding the 65535 bytes limit

See previous post about -X options. But it if you do not want to improve parser organization then it is much better to split the grammar up in to a number of 'import' grammars, which will reduce individual class size. You do not want to apply scripts to generated code really :-(
