> Using the annotation @MapKeyJoinColumns always throws an exception, which is obvious when you look at AnnotationBinder.java (line 1772 in 3.5.6):
> if ( property.isAnnotationPresent( MapKeyJoinColumns.class ) ) {
> 	stuff...
> 	joinKeyColumns = new JoinColumn[mapKeyJoinColumns.length];
>         stuff...
> 	if ( joinKeyColumns != null ) {
> 		throw new AnnotationException(
> 				"@MapKeyJoinColumn and @MapKeyJoinColumns used on the same property: "
> 						+ BinderHelper.getPath( propertyHolder, inferredData )
> 		);
> 	}
> }
> The problem here is that the if statement is always true because joinKeyColumns was created as non-null above.
