One-to-many relationship to class with JOINED inheritance causes assertion failure in JoinedSubclassEntityPersister ------------------------------------------------------------------------------------------------------------------- Key: HHH-5241 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5241 Project: Hibernate Core Issue Type: Bug Affects Versions: 3.5.0-CR-1 Environment: Hibernate 3.5.0-CR1 (included with JBoss Application Server 6.0.0 M2) SQL Server 2005 Reporter: Stu White Attachments: testcase.zip I've created a JPA mapping for a class that has a one-to-many relationship via a join table to other classes which are using a JOINED inheritance strategy, and I'm getting an odd error which makes me wonder whether I've come across a bug in Hibernate. The particular error I'm getting is: Exception in thread "main" 2010-05-20 10:00:04,783 - an assertion failure occured (this may indicate a bug in Hibernate, but is more likely due to unsafe use of the session) org.hibernate.AssertionFailure: Table JpaTest.ParentOwnerJoinTable not found at org.hibernate.persister.entity.JoinedSubclassEntityPersister.getTableId(JoinedSubclassEntityPersister.java:497) at org.hibernate.persister.entity.JoinedSubclassEntityPersister.<init>(JoinedSubclassEntityPersister.java:276) at org.hibernate.persister.PersisterFactory.createClassPersister(PersisterFactory.java:87) at org.hibernate.impl.SessionFactoryImpl.<init>(SessionFactoryImpl.java:272) at org.hibernate.cfg.Configuration.buildSessionFactory(Configuration.java:1385) at org.hibernate.cfg.AnnotationConfiguration.buildSessionFactory(AnnotationConfiguration.java:974) at org.hibernate.ejb.Ejb3Configuration.buildEntityManagerFactory(Ejb3Configuration.java:850) at org.hibernate.ejb.HibernatePersistence.createEntityManagerFactory(HibernatePersistence.java:56) at javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:48) at javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:32) at com.i2group.jpatest.JpaTestBase.createEntityManager(JpaTestBase.java:51) at com.i2group.jpatest.JpaOwnershipInheritanceTest.writeEntity(JpaOwnershipInheritanceTest.java:28) at com.i2group.jpatest.JpaOwnershipInheritanceTest.main(JpaOwnershipInheritanceTest.java:22) I've attached a zip containing the classes, persistence XML, and SQL Server setup script. The classes are: Owner The owner linked by a one-to-many relationship to Parent/ChildOne/ChildTwo Parent Parent class using a JOINED inheritance strategy ChildOne Child of Parent ChildTwo Child of Parent The error only seems to occur when combining a one-to-many relationship via a join table to a class using inheritance. If I remove the link to Owner and just test the inheritance of Parent/ChildOne/ChildTwo then it works fine. If I remove the inheritance and just test the one-to-many relationship from Owner to Parent then it works fine. If I try to combine the two then I get the error above. I don't think I'm doing anything particularly obscure, which makes me suspicious that this is more likely to be a mistake in my configuration than a bug in Hibernate. However, I've checked the configuration and tested parts of it separately and have been unable to find what (if anything) I'm doing wrong. If there's any further information I can provide to help diagnose this then please let me know. -- 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
