[antlr-interest] java.lang.StackOverflowError

[Andreas Meyer]

You could  try to increase the time-out, I think it was called 
-Xconversiontimeout. In my grammar, I have to set it to 20 seconds until 
it works without error. It does not generate huge code, it just takes 
some time to find out to do nothing.
