Mapping of inheritance with several generic superclasses fails
--------------------------------------------------------------

         Key: ANN-416
         URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-416
     Project: Hibernate Annotations
        Type: Bug

  Components: binder  
    Versions: 3.2.0.cr1    
 Environment: Hibernate: 3.2.0.cr2
    Reporter: Amelin Dmitry
 Attachments: testcase.zip

Classes and mapping code:

@MappedSuperclass
public abstract class OrganizationData<T extends OrganizationData> {
    @OneToOne
    private T update;

    // Getters and Setters
    ...
}

@MappedSuperclass
public abstract class ContactData<T extends ContactData> extends OrganizationData<T> {
}

@Entity
public class Phone extends ContactData<Phone> {
    // code
    ...
}


Full stack trace of any exception that occurs:

java.lang.IllegalStateException: Property update has an unbound type and no explicit target entity.

Important note:
If Phone class inherits OrganizationData directly, all works fine.
