I imagine that's not a legal MDB (having not looked at the spec on that detail, but it would surprise me if this was legal). Recall, the MDB is owned and managed by the container, so it provides the semantics and lifecycle of the MDB, and the MDB must be built with the containers restraints and requirements in mind.
