[antlr-interest] Parse failing, not sure why

I'm writing a grammar for Small-C. 

As far as I can tell, my grammar matches the language specification. 

ANTLR generates the Java code with no hiccups. 

However, in the interpreter, ANTLR does not seem to be matching rules that it could match, and instead is returning mismatch exceptions. 

Glaring example: 


    return 1;

The interpreter sends back: 

MismatchedTokenException: line 1:5 mismatched input ')' expecting '\u0016'

But this rule should match: 

main : MAIN LPAREN RPAREN body ;

What could be causing this?

Does rule declaration order make a difference?

Grammars are attached.
