Description

Class OrderBy represents a list of ORDER BY clauses and is defined as

public class OrderBy<P, V> implements QueryProcessor<P> {
    public void add(SingularAttribute<? super P, V> att, OrderDirection dir)
}

where P is an entity type and V is a value type.

This does not really make sense, since ORDER BY clauses do not have a common type in general (e.g. ORDER BY date DESC, name ASC).

The issue is glossed over in QueryCriteria by using OrderBy as a raw type.
