Hello, i am using Hibernate 3.3.1. (JBoss 5.1.0)
I tried to debug Hibernate for a possible bug. But the package "org.hibernate.hql.antlr" is empty. The package.html says

The classes in this package are generated from the ANTLR grammar files, do not register them into version control

How to create the package source code so that I can debug it?

when I run

> mvn install

....
