After adding a parent entity like
{code:java}@Entity
@Audited
@Inheritance(strategy·=·InheritanceType.TABLE_PER_CLASS)
public a {
}{code}
to a pre-existing entity
{code:java}@Entity
@Table(name = "b")
@Audited(withModifiedFlag = true)
@AuditTable(value = "bAudit")
public class b extends a {
}{code}
The following excpetion exception pops up and the application fails to start:
{code:java}Caused by: java.lang.ClassCastException: class org.hibernate.mapping.Table cannot be cast to class org.hibernate.mapping.DenormalizedTable (org.hibernate.mapping.Table and org.hibernate.mapping.DenormalizedTable are in unnamed module of loader 'app')

The mapping works and the exception goes away if the @AuditTable annotation is and the @Table annotations removed removed from class “b”.
