[antlr-interest] Java parser not compiling

[Kirby Bohling]

Not that I want to advocate forking, but with git, it should be easy
to maintain ANTLR patches for bugfixes.  I regularly maintain 3rd
party code in local git repos with bug fixes which haven't been put
into a mainline release.  It easy for folks to pickup fixes they want,
and maintain them in tree, with history, and provenance about where
all the code came from.  Publish to github or bitbucket, and we it'd
be a service to the community.
