Entity with several generic superclasses mapping problem

Hibernate version: 3.2.0.cr2

Mapping documents: Annotations 3.2.0.cr1

Classes and mapping code:

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:

Code:

java.lang.IllegalStateException: Property update has an unbound type and no explicit target entity.
        at org.hibernate.cfg.AnnotationBinder.addElementsOfAClass(AnnotationBinder.java:938)
        at org.hibernate.cfg.AnnotationBinder.getElementsToProcess(AnnotationBinder.java:788)
        at org.hibernate.cfg.AnnotationBinder.bindClass(AnnotationBinder.java:614)
        at org.hibernate.cfg.AnnotationConfiguration.processArtifactsOfType(AnnotationConfiguration.java:353)
        at org.hibernate.cfg.AnnotationConfiguration.secondPassCompile(AnnotationConfiguration.java:265)
        at org.hibernate.cfg.Configuration.buildSessionFactory(Configuration.java:1205)
...

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

Am I missing something?
