Just a guess: Does your top level production (program or script or some such) end with the  
token EOF?  Bet not....

Without the EOF token at the end of the top level rule, Antlr doesn't need to match the 
whole input.  So, it is happily matching the first part of the input and returning the tree for  
that.
