Message Title

Annotating a byte[] field with @NaturalId causes a ClassCastException when trying to persist the entity. This happens because SimpleNaturalIdMapping.validateInternalForm tries to cast the primitive array to Object[].
class [B cannot be cast to class [Ljava.lang.Object; ([B and [Ljava.lang.Object; are in module java.base of loader 'bootstrap')
java.lang.ClassCastException: class [B cannot be cast to class [Ljava.lang.Object; ([B and [Ljava.lang.Object; are in module java.base of loader 'bootstrap')
