please see the doc of getByUUID:
This method is intended for replication and for long-term external references to objects. To get a Db4oUUID for an object use getObjectInfo(Object) and ObjectInfo.getUUID().
Objects will *NOT* be activated by this method. They will be returned in the activation state they are currently in, in the local cache.
So it needs explicit activation by the user code, db.activate(obj, depth);
