Cascade delete does not work with unidirectional @OneToMany and @JoinTable
--------------------------------------------------------------------------

                 Key: HHH-3008
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3008
             Project: Hibernate3
          Issue Type: Bug
    Affects Versions: 3.2.5
         Environment: Standalone entity manager (JavaSE 5.0).
H2 database.
            Reporter: Daniel Dyer


A unidirectional one-to-many relationship defined as follows:

public class Owner
{
    @OneToMany(cascade = CascadeType.ALL)
    @JoinTable(name = "owner_element",
               joinColumns = @JoinColumn(name = "owner_id",
                                         nullable = false,
                                         updatable = false),
               inverseJoinColumns = @JoinColumn(name = "element_id",
                                                nullable = false,
                                                updatable = false))
    private List<Element> elements;

    // ...
}

Attempting to delete an instance of Owner should also delete all associated instances of Element.  Instead I get the following error:

SEVERE: Referential integrity constraint violation: FK56BBF9C487E817D: PUBLIC.OWNER_ELEMENT FOREIGN KEY(OWNER_ID) REFERENCES PUBLIC.OWNER(ID) [23003-63]

This is because Hibernate attempts to delete the Owner row without first removing the rows from the join table.
