[hibernate-issues] [Hibernate-JIRA] Updated: (HHH-4036) EntityMetamodel entityNameByInheritenceClassNameMap field used inconsistently

EntityMetamodel entityNameByInheritenceClassNameMap field used inconsistently ----------------------------------------------------------------------------- Key: HHH-4036 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-4036 Project: Hibernate Core Issue Type: Bug Components: core Affects Versions: 3.3.2 Reporter: Jeremy Stone Attachments: HHH-4036.patch After upgrading (from 3.3.0.SP1) to 3.3.2.GA we have started getting the follow stack trace logged: org.hibernate.HibernateException: Unable to resolve entity name from Class [com.cyclone.netPrefect.admin.restriction.complex.TimeSpanRestrictionItemEntity] expected instance/subclass of [RestrictionItem] at org.hibernate.tuple.entity.PojoEntityTuplizer.determineConcreteSubclassEntityName(PojoEntityTuplizer.java:363) at org.hibernate.persister.entity.AbstractEntityPersister.getSubclassEntityPersister(AbstractEntityPersister.java:3643) at org.hibernate.impl.SessionImpl.getEntityPersister(SessionImpl.java:1375) at org.hibernate.engine.ForeignKeys.isTransient(ForeignKeys.java:203) at org.hibernate.event.def.AbstractSaveEventListener.getEntityState(AbstractSaveEventListener.java:535) at org.hibernate.event.def.DefaultSaveOrUpdateEventListener.performSaveOrUpdate(DefaultSaveOrUpdateEventListener.java:103) ... etc, etc The com.cyclone.netPrefect.admin.restriction.complex.TimeSpanRestrictionItemEntity is mapped (with entity name TimeSpanRestrictionItem) as a joined subclass of the entity named RestrictionItem. I have had a look at the Hibernate source for 3.3.2.ga and it looks like problem is the way that the org.hibernate.tuple.entity.EntityMetamodel is using it entityNameByInheritenceClassNameMap field: * Puts to the map are based on PersistentClass.getMappedClass() as a key - a Class object * Gets from the map (in findEntityNameByEntityClass method) are using the class name Presumably (given the name of the map field) both put and get should be using the class name.
