Laird Nelson ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) *created* an issue Hibernate ORM ( https://hibernate.atlassian.net/browse/HHH?atlOrigin=eyJpIjoiYTg5NmI2MjYx... ) / Bug ( https://hibernate.atlassian.net/browse/HHH-15738?atlOrigin=eyJpIjoiYTg5Nm... ) HHH-15738 ( https://hibernate.atlassian.net/browse/HHH-15738?atlOrigin=eyJpIjoiYTg5Nm... ) Hibernate's EntityManager#persist(Object) implementation can throw PersistenceException, which the spec does not permit ( https://hibernate.atlassian.net/browse/HHH-15738?atlOrigin=eyJpIjoiYTg5Nm... ) Issue Type: Bug Affects Versions: 6.1.4 Assignee: Unassigned Components: hibernate-core Created: 21/Nov/2022 10:23 AM Environment: Hibernate 6.1.4, though I suspect this problem has existed for a long time Priority: Major Reporter: Laird Nelson ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) To reproduce: * Put an entity into the persistence context, then remove it. Now you have a detached entity. * Call EntityManager#persist(Object) with the detached entity. * Observe that Hibernate throws a PersistenceException. Note that the javadocs ( https://jakarta.ee/specifications/persistence/3.1/apidocs/jakarta.persist... ) do not permit this kind of exception to be thrown. Perhaps an IllegalArgumentException should be thrown instead?
