[stringtemplate-interest] Working Java 1.5 grammar?

[Steven Atkinson]

Folks,

I'm trying to get a working Java 1.5 grammar and tree walker for source-to-source refactoring efforts at Netflix.

I've installed antlrWorks in IntelliJ, downloaded the Java.g from antlr.org, and even went hunting in openJDK sources for a working ANTLR v3 grammer for Java 1.5 or 1.6.

When I try putting the Java.g grammar from Yang Jiang<http://openjdk.java.net/projects/compiler-grammar/antlrworks/Java.g> (yang.jiang.z at gmail.com<mailto:yang.jiang.z at gmail.com>) through ANTLRWorks or on the command line I get the following error output

Any help is appreciated!
