caching ejb3 entities tutorial demo does not work in JBoss 6

I run this demo: http://docs.jboss.org/ejb3/docs/tutorial/1.0.7/html/Caching_EJB3_Entities.html
in jboss 6 and it fails:

Caused by: org.hibernate.HibernateException: could not instantiate RegionFactory [org.hibernate.cache.jbc2.JndiMultiplexedJBossCacheRegionFactory]
