I am using JBoss Tools 3.2.2.CR1. When I try to use Schema Export via the Hibernate Code Generation window, I get the following exception:

org.hibernate.console.HibernateConsoleRuntimeException: Received a NoClassDefFoundError, probably the console configuration classpath is incomplete or contains conflicting versions of the same class

According to Max "that looks like a big regression bug". See forum reference below.
