> I got a class composite id class for a table with @Embeddable.
> It has two properties, and the equals and the hashCode methods.
> When hibernate-jpamodelgen 1.1.1.Final generates the metaclasses, I got a SingularAttribute with the name "hashCode" generated. But hashCode is not a property in the entity.
