This zip file contains the source files that are part of antlr, but not self contained.  i.e. They depend on either the StringTemplate library or on a previous version of ANTLR that cannot be checked in on an Eclipse Server.  The actual classes are not required by EclipseLink, but the source files have been kept in case they are needed when the grammar is regenerated.

They should be capable of compiling against a full version of ANTLR v3
