Ok seems like the right place. (StorageManager) NullPersistenceManager does (or doesn't do) what it says on the can - no persistence. That means no persistence at all: 1) No message journal 2) No bindings journal 3) No paging 4) No storing large messages outside the journal. It is designed for people who do not (or cannot) use the filesystem (e.g. in applet or sandbox or embedded) so no file system access should be attempted.
