--------------------------------------------------------------------
I don't know if the loadedState should be used in this case, but if it should, then the problem occurs because in file DefaultSaveOrUpdateEventListener there is a null value send to
source.getPersistenceContext().addEntity(
entity,
( persister.isMutable() ? Status.MANAGED : Status.READ_ONLY ),
null, //cachedSate
...
There is even a comment that you there is some extra work needed to load cachedState...
I tried to resolve the cachedState in some "dirty hack" (I don't know the inner logic of hibernate yet), and then it worked, but it did broke 5 other test cases ;)

> The NPE is thrown because "loadedState" field is null. The exception seems to occur for instance when we have OneToOne with Cascade.DELETE_ORPHAN (or orphanRemoval="true"), CascadeType.SAVE_UPDATE and CascadeType.DELETE.
> I will try to create a simple example to reproduce the problem.
