I have been working with a wrapper around htmlunit ( 2.32) it appears that the Document traversal is failng to stop at the root node during its back tracking.  there appears to be no check to see if the 

I have attached an example.  in this example i am searching a table from the td id='11' . 

I suspect the issue is in th DomeNodeIterator.getFirstUncle,   i *believe* this 
        final DomNode parent = node.getParentNode();
        if (parent == null) {
            return null;
        }
        
        should read
        
        final DomNode parent = node.getParentNode();
        if (parent == null || parent == root) {
            return null;
        }
