    Description

      Using RC1 of lucene 2.4 resulted in null pointer exception with some constructed SpanNearQueries

      Implementation of isPayloadAvailable() (results in exception)

       public boolean isPayloadAvailable() {
         SpansCell pointer = min();
         do {
           if(pointer.isPayloadAvailable()) {
             return true;
           }
           pointer = pointer.next;
         } while(pointer.next != null);
      
         return false;
        }
      

      "Fixed" isPayloadAvailable()

       public boolean isPayloadAvailable() {
         SpansCell pointer = min();
         while (pointer != null) {
           if(pointer.isPayloadAvailable()) {
             return true;
           }
           pointer = pointer.next;
         }
      
         return false;
        }
      

      Exception produced:

      will attach unit test that causes exception (and passes with updated isPayloadAvailable())
