Forward port to Trunk: ReferringDocumentsProvider should use path instead of node name in sorting method

Forward port CMS-9621 to trunk: ReferringDocumentsProvider should use path instead of node name in sorting method

Right now it reports wrong number of referred documents.
method:
private static SortedSet<Node> getSortedReferrers(final Collection<Node> nodes) throws RepositoryException {
final TreeSet<Node> sorted = new TreeSet<>(new Comparator<Node>() {
@Override
public int compare(final Node node1, final Node node2)

{ try { return node1.getName().compareTo(node2.getName()); }

catch (RepositoryException e)

{ throw new RepositoryRuntimeException(e); }
}
});
sorted.addAll(nodes);
return sorted;
}



should be:

private static SortedSet<Node> getSortedReferrers(final Collection<Node> nodes) throws RepositoryException {
final TreeSet<Node> sorted = new TreeSet<>(new Comparator<Node>() {
@Override
public int compare(final Node node1, final Node node2) {
try { return node1.getPath().compareTo(node2.getPath()); } catch (RepositoryException e) { throw new RepositoryRuntimeException(e); }

}
});
sorted.addAll(nodes);
return sorted;
}
