SINGLE_TABLE inheritance: PersistentCollectionChangeWorkUnit.java: string truncating is used to find a property name from a collectionEntry
-------------------------------------------------------------------------------------------------------------------------------------------

                 Key: HHH-3717
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3717
             Project: Hibernate Core
          Issue Type: Bug
         Environment: envers 1.1.0 GA
            Reporter: Michele Comitini


in PersistentCollectionChangeWorkUnit.java string truncating is used to find a property name from a collectionEntry.  It seems that if the entity is derived
with SINGLE_TABLE inheritance this truncating is fault prone.

I attached a quick patch that seems to fix the problem, but I think manipulating strings is still not too safe to find the correct property name...

Here is an excerpt of code that happens to fail:

@Entity
@Versioned
@Table(name = "notifica")
@Inheritance(strategy=InheritanceType.SINGLE_TABLE ) 
@NamedQueries({
    @NamedQuery(name="Notifica.all", query="from Notifica"),
})
public class Notifica extends BaseCQOPEntity implements Persistent
{
	private static final long serialVersionUID = -7096378249035298397L;

	@Id
	@GeneratedValue
	@XStreamAlias("idd")
	private Long id;

	
	@Where(clause="not(deleted=(1=1))")
	@OneToMany(fetch=FetchType.EAGER)
	@Cascade({})
	private Set<Ruolo> ruoli = new HashSet<Ruolo>();

        .
        .
        .

}


@Entity
@Versioned
@DiscriminatorValue(value="Pratica") 
public class NotificaPratica extends NotificaImpresa
{
	private static final long serialVersionUID = 1L;
        .
        .
        .
}
