This is due to the approximate-LL(k) lookahead issue in ANTLR2 if 
memory serves.

My advise?, check the relevant part of the generated code manually to 
ensure it is indeed doing what you want (and changing it if it 
isn't). That's one of the strengths of ANTLR, the generated code is 
human-readable....
