[antlr-interest] error(10): internal error: TWalker.g : java.lang.IllegalArgumentException: Can't find template tokenRefRuleRoot.st

[Cameron Palmer]

This is a painful error because it seems to be meaningless. In my
grammar I eliminated the error by finding places that I got carat
happy:

rule : x^ this that
       | y^
       ;

CHANGED TO

rule : x^ this that
       | y
       ;
