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@gmail.com<mailto:yang.jiang.z@gmail.com>) through ANTLRWorks or on the \
command line I get the following error output
Any help is appreciated!
