> Defining UniqueConstraint on MappedSuperClass fails with NPE [1]
> @MappedSuperclass
> @Table(uniqueConstraints={@UniqueConstraint(columnNames={"ATTR_NAME", "OWNER"})})
> public abstract class Attribute<T> { 
> While it is debatable a @Table annotation is appropriate for @MappedSuperClass, the situation must be detected and warned more gracefully than a NPE.
> Also investigate whether UniqueConstraint on a MappedSuperClass should be supported.
