[hibernate-issues] [Hibernate-JIRA] Created: (EJB-382) PersistenceException instead of EntityExistsException thrown when entity already exists

PersistenceException instead of EntityExistsException thrown when entity already exists --------------------------------------------------------------------------------------- Key: EJB-382 URL: http://opensource.atlassian.com/projects/hibernate/browse/EJB-382 Project: Hibernate Entity Manager Issue Type: Bug Components: EntityManager Affects Versions: 3.4.0.GA Reporter: Miro Bezjak Priority: Minor Attachments: hibernate.zip By specification of EntityManager (http://java.sun.com/javaee/5/docs/api/javax/persistence/EntityManager.htm...) an EntityExistsException should be thrown when entity already exists but current implementation of AbstractEntityManagerImpl throws PersistenceException. I noticed the bug when upgrading from 3.3.2.GA (throws EntityExistsException properly) to 3.4.0.GA. It seems that problem is in throwPersistenceException method. 3.3.2.GA has following code: " else if ( e instanceof ConstraintViolationException ) { //FIXME this is bad cause ConstraintViolationException happens in other circumstances throwPersistenceException( new EntityExistsException( e ) ); } " but that was dropped in 3.4.0.GA (maybe because of http://opensource.atlassian.com/projects/hibernate/browse/EJB-349 ?). Anyway, stack trace for attached example: javax.persistence.PersistenceException: org.hibernate.exception.ConstraintViolationException: could not insert: [test.User] at org.hibernate.ejb.AbstractEntityManagerImpl.throwPersistenceException(AbstractEntityManagerImpl.java:614) at org.hibernate.ejb.AbstractEntityManagerImpl.persist(AbstractEntityManagerImpl.java:226) -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira
