You can't turn it off, and it is not causing your problem. The  
comments are
just annotations and are comments after all.

You do have a rule called 'package', right?

I guess that Java doesn't like that as a method name (which ANTLR  
will turn
parser rule names into). I suggest renaming that rule.

Please provide the complete error message in your posts (or at least  
the line number
reported). It took me a while of hard staring to sort through the  
wrapped source code
to actually figure out why this code would be invalid or where the  
error was supposed
to be.

HTH,
