Hierarchical container sorting

I had a problem sorting a tree, by using
HierarchicalContainer.sort
.

the code of this method is

[code]
@Override
protected void doSort() {
super.doSort();

    Collections.sort(roots, getItemSorter());
    for (LinkedList<Object> childList : children.values()) {
        Collections.sort(childList, getItemSorter());
    }
}

[/code]I do not understand the call to super (so the
IndexedContaioner
 implementation), as it will sort all items, whether or not they do have a ‘brother’ relation ship.

looks to me more like a bug, as it is completly useless, but I may have miss something.

Thanks
