If the setSelectedNodes() method is invoked with a node not existing below the
current root context, the checkAndSet() method of the inner class creates a new 
list instance for valid nodes and copies over previously validated nodes;
however, the copy loop uses the wrong index variable (i instead of j), thus 
repeatedly adding the same node:


               if (!isUnderRoot(value[i])) {
                   if (validNodes == null) {
                       validNodes = new ArrayList<Node>(value.length);
                       for (int j = 0; j < i; j++) {
---->                       validNodes.add(value[i]);   <-----
                       }
                   }
