[antlr-interest] Grammar generation results in exception

[Johannes Luber]

Hello!

I've been working on a ANTLR3-to-RelaxNG converter based on Terence's
ANTLRv3.g. When I want to generate the corresponding C#-files, I receive
following output:

ANTLR Parser Generator  Version 3.0 (May 17, 2007)  1989-2007

Lies the error with mine code or is it an ANTLR bug? The file is
attached. And if I didn't change the license text correctly, please let
me know!

Best regards,
Johannes Luber
