Test case: https://github.com/arosinijc/hibernate-map-entity
The problem seems to be that when a DynamicMapEntityTupilzer is registered, it applies itself to any entity which matches Map.class.isInstance( entity ). Since the entity in question passes that check, but doesn't provide its entity type under the $type$ key, org.hibernate.tuple.entity.DynamicMapEntityTuplizer.BasicEntityNameResolver#resolveEntityName(Object) throws the following exception:

If the entity isn't marked as {Audited, no map entities are ever registered and so no DynamicMapEntityTupilzer is ever registered and the entity is able to be persisted. I suspect this has nothing to do with envers other than that registration, which could happen with any entity which is map mode. |
