To the lexer options. It is probably exiting due to encountering a
character outside the character vocabulary defined in the lexer rules
so far. Although I'd suspect that it should print an error message
about encountering an exception during lexing.
BTW the default charVocabulary will change to the above in the 2.7.5
release of antlr.
