[clay] closing urlconnections

[Ryan Wynn]

I noticed that in Clay's ComponentConfigBean$WatchDog the following is
used to close the open URLConnections:

private void close() {
           if (connections == null) {
               return;
           }

           for (int i = 0; i < connections.length; i++) {
               connections[i] = null;
           }

           connections = null;
       }

Is dereferencing these enough or would it be better to explicitly call
close() on the inputstreams associated with the connections?
