>             Project: Hibernate Core
>          Issue Type: Bug
>          Components: core
>    Affects Versions: 3.1 rc2
>            Reporter: Richard HALLIER
>            Assignee: Steve Ebersole
>             Fix For: 3.1

> Example :
> 		<set name="items" inverse="true" sort="com.ItemComparator">
> 			<key column="x_id"/>
> 			<one-to-many class="com.Item"/>
> 		</set>
> Hibernate doesn't initialize correctly the sorted set, the comparator is not set.
> I think it comes from the following method of the Collection class :
> public Comparator getComparator() {
> 		if(comparator!=null && comparatorClassName!=null) {
> 			try {
> 				setComparator( (Comparator) ReflectHelper.classForName(
> 					comparatorClassName ).newInstance() );
> 			}
> 			catch (Exception e) {
> 				throw new MappingException( "Could not instantiate comparator class: "
> 					+ comparatorClassName + " for collection " + getRole()  );
> 			}
> 		}
> 		return comparator;
> 	}
> It obviously should be :
> 		if(comparator==null && comparatorClassName!=null) {
