[hibernate-issues] [Hibernate-JIRA] Created: (HHH-5241) One-to-many relationship to class with JOINED inheritance causes assertion failure in JoinedSubclassEntityPersister
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

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.
