ObjectDB knows to build missing entity and embeddable classes, based on the schema that is internally ... the mismatching.

Discovered that you can't embed entities in embeddable objects if the entity is managed. Haven't tried embedding un-managed entities in embeddable objects, though I imagine that's not a great idea. The the error message isn't all that obvious (attempting to persist object which already has an id
