oups, message sent too quickly ... SUPPORTS is usually fine as a default for "finder" methods. As soon as there is no transaction, an entity is detached when returned by the entity manager. Even with SUPPORTS btw
When REQUIRED (or any transaction) is used, the entity remains attached and managed my the persistence context till the end of the transaction by default. For an EPC in a Stateful, it's a bit different. So I'd say you have the desired behavior as per the spec.
