Test Network Genesis Block

I am using BitcoinJ for my java application which fetches the test network’s genesis block. I referred to the basics mentioned at JavaWorld and BitcoinJ’s Google Code wiki.

I am able to get it running but there seems to be an error while waiting for the node.

I receive the following output :

Note: I am working from a NAT network, can this be a point of connection failure?
