@MapKeyJoinColumns always throws an exception
---------------------------------------------

                 Key: HHH-5940
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5940
             Project: Hibernate Core
          Issue Type: Bug
          Components: annotations
    Affects Versions: 3.5.6
            Reporter: Bob Reynolds


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.
