Are you using the debugger or the interpreter to test with? The
interpreter doesn't execute predicates, so it won't work properly;
you need to use the debugger.
It also might pay to try a few variations on the ENDOFLINE rule;
sometimes ANTLR seems to ignore predicates if it thinks that
they're not accomplishing anything. Try this, for example:
fragment ENDOFLINE : { input.LA(1) == EOF }? => | NEWLINE ;
or this:
fragment ENDOFLINE : NEWLINE | EOF ;
