[antlr-interest] lexer doesn't see super constructor & inherited variable

[Raphael Reitzig]

Hi Johan!

Do you use Java 6 for compilation? I do not know if it makes a  
difference here, but one never knows. I experienced some strange  
behaviour trying to compile code with 1.5 that worked perfectly with 6.

Regards

Raphael
