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

Ed Bras commented on HHH-4036:
------------------------------
Oeppsss sorry was a bit too fast (still an interesting post that you can use as a work
around like I do).
Anyway: the following method in EntityMetamodel:
public String findEntityNameByEntityClass(Class inheritenceClass) {
return ( String ) entityNameByInheritenceClassNameMap.get( inheritenceClass.getName()
);
}
Should be replaced by:
public String findEntityNameByEntityClass(Class inheritenceClass) {
return ( String ) entityNameByInheritenceClassNameMap.get( inheritenceClass );
}
Just like you mention above...
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
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]

... 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.
