Issue Type: Bug Affects Versions: 5.4.15 Assignee: Unassigned Created: 03/Jun/2020 09:55 AM Priority: Major Reporter: Alex CD ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%3A9b0f6d49-bc76-4aca-875b-c8525b2f039d )

*Person* entity references one *Nickname* entity having foreign key *on delete set null*.

If Person _entity is stored in second level cache and her _Nickname entity is deleted by a native query, then the reference id is set to null in database, but the cached Person entity still has the old reference id.

Loading the Person from second level cache (entitymanager.find) tries to load the old Nickname that doesn't exist, throws EntityNotFoundException that cascades and ultimately returns a *null Person* object.

Person entity still *exists* in database and should have been found and the invalid reference should be resolved somehow (maybe recheck in database).
