PersistentClass.checkColumnDuplication does not honor @Column.table
-------------------------------------------------------------------

                 Key: HHH-5586
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5586
             Project: Hibernate Core
          Issue Type: Bug
          Components: core
    Affects Versions: 3.3.1
         Environment: hibernate 3.3.1.GA packaged with jboss 5.1.0.GA

            Reporter: Jürgen


similar column names in main and a secondary table triggers MappingException:
org.hibernate.MappingException: Repeated column in mapping for entity
in case of javax.persistence.InheritanceType.TABLE_PER_CLASS

seems to me as if org.hibernate.mapping.PersistentClass.checkColumnDuplication(Set, Iterator) does not consider javax.persistence.Column.table() value for duplication check.

{code}
Caused by: org.hibernate.MappingException: Repeated column in mapping for entity: com.example.AAAX column: col1 (should be mapped with insert="false" update="false")

{code}

Following entity model (nevermind the inheritance, it a legacy db mapping)

{code}
@Entity
@Inheritance(strategy = InheritanceType.TABLE_PER_CLASS)
abstract class A {}

@Entity
@Table(name="AA")
@Inheritance(strategy = InheritanceType.SINGLE_TABLE)
@DiscriminatorFormula(value="discriminator")
abstract class AA extends A {
  @Column(name = "col1")
  protected String col1;
}

@Entity
@SecondaryTable(name = "T", pkJoinColumns=@PrimaryKeyJoinColumn(name="a"))
abstract class AAA extends AA {
  @Column(name = "col1", table="T")
  protected String Tcol1;
}

@Entity
@DiscriminatorValue(value="AAX")
public class AAAX extends AAA {
}
