Sort a java.util.Set or java.util.Map in its natural order

Sorting is performed in memory, by Java's java.util.TreeSet or java.util.TreeMap, and is maintained by any operation that mutates the collection.

• Use SortComparator to sort the collection in memory using a java.util.Comparator.
• Use jakarta.persistence.OrderBy to order using an expression written in HQL.
• Use SQLOrder to order using an expression written in native SQL.

It is illegal to use both SortNatural and SortComparator.
