You're right about the docs. It's an area that can be improved. You're not *deploying* the cache from an EJB, right? It should be a separate deployment, either standalone or packaged with the ejb jar(s) in an ear or a sar. If not deploying the cache from the EJB, you're not creating threads from the EJB either, and there is no issue using the cache from the EJB.
