The second param is whether the cache manager should create the "mvcc-entity" cache if not already created. Whether you pass true or false depends on whether you want a guaranteed non-null return.

Thanks!

  | Hibernate provides an API (Statistics) for inspecting the Second Level Cache. See http://www.hibernate.org/hib_docs/v3/reference/en-US/html/performance-sessioncache.html. Users should restrict themselves to that API. If an existing EJB3 example pokes around in the cache internals, I encourage you to convert it to use the Hibernate Statistics API.

That's exactly what i was trying to refactor in the EJB3 tutorial :-) Thanks for the pointer to Hibernate Statistics API. I'll take a look.
