MappedSuperclass in the middle of class hierarchy - column not found
--------------------------------------------------------------------

                 Key: HHH-5060
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5060
             Project: Hibernate Core
          Issue Type: Bug
          Components: core
    Affects Versions: 3.5.0-CR-2
            Reporter: bogdan
         Attachments: mappedsuperclasstestcase.zip

We've got model with MappedSuperclass in the middle of class hierarchy:
Person(Entity) -> EmployeeBasic(MappedSuperclass) -> Employee(Entity) -> BossBasic(MappedSuperclass) -> Boss(Entity)

Following exception occurs when we run query: "SELECT p1 FROM Employee p1", which should return instances of Employee and Boss (attached: test.CMappedSuperclassTestCase.testSimpleQueryModel()):

javax.persistence.PersistenceException: org.hibernate.exception.SQLGrammarException: could not execute query
	at org.hibernate.ejb.AbstractEntityManagerImpl.convert(AbstractEntityManagerImpl.java:1167)
	at org.hibernate.ejb.AbstractEntityManagerImpl.convert(AbstractEntityManagerImpl.java:1100)
[...]
Caused by: java.sql.SQLException: Column not found: OWNED11_1_
	at org.hsqldb.jdbc.Util.sqlException(Unknown Source)

Query against the same model works well when we eliminate MappedSuperclass from hierarchy (attached: test.CMappedSuperclassTestCase.testSimpleQueryModel2()).

Issue didn't occure in previous release: 3.3.2.GA.
