This is because "LT" is the name of an internal function
(specifically, one that gets a specific Lookahead token Type).

Problems in there are probably either due to recursive or
zero-consuming token definitions, although I didn't spot any of
those in the grammar you attached.

I'm not sure what the problem would be here. Have you tried
compiling the library in debug mode so that you can step through
the code and work out what it's doing?
And which version of ANTLR and the runtime are you using? Are you
sure the versions match?
