> 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.
