Suspicious code

[Dave Brosius]

In org.apache.xindice.xml.dom.traversal.TreeWalkerImpl is this code   Clearly this is wrong:            if ( node == null )             node = node.getParentNode();          public Node previousNode() {       Node node = next;       while ( true ) {          node = node.getPreviousSibling();          if ( node == null )             node = node.getParentNode();          else             while ( node.hasChildNodes() )                node = node.getLastChild();          if ( node != null && acceptNode(node) ) {             next = node;             return next;          }          else if ( node == null )             return null;       }    }
