Annadurai Narayanan commented on ISPN-1210:
-------------------------------------------

find the problem in TreeCacheImpl.java at line 338. 

public Map<K, V> getData(Fqn fqn) {
      startAtomic();
      try {
         Node<K, V> node = getNode(fqn);
         if (node != null) // node is not null then return the node.getData()
            return null; // this is wrong.
         else
            return node.getData();
      }
      finally {
         endAtomic();
      }
   }
