I just had a quick look at the generated source for the lexer in your
project. It seems to have been generated by a pre-SP1 version of
ANTLR/C# 2.7.2.

In the method initialize(), the SP1 version generates code to create
the literals table with a line like:

literals = new Hashtable(CaseInsensitiveHashCodeProvider.Default,
CaseInsensitiveComparer.Default);

This is not the case with your project. Did you have some problem with
building ANTLR/C# (after you applied SP1)?. ANTLR 2.7.2 has it's own
build tool. Please see the installation docs supplied with ANTLR for
info about the build tool. The C# runtime library will then need to be
built separately.

Cheers,
