When starting a cluster via testing, I want to get the bounded port since I  
am letting choose and there might be a conflict.

Here is the ugly and brittle code I came up to do this:

Is there a nicer API than having to regex out the connection string?

Thanks,  
Paul

Not sure why you convert the "publish" address to a string, in Java you can  
find the current transport port with

```
    // find node address
    NodesInfoRequest nodesInfoRequest = new

```

NodesInfoRequest().transport(true);  
NodesInfoResponse response =  
client.admin().cluster().nodesInfo(nodesInfoRequest).actionGet();  
Object obj =  
response.iterator().next().getTransport().getAddress().publishAddress();  
if (obj instanceof InetSocketTransportAddress) {  
InetSocketTransportAddress address =  
(InetSocketTransportAddress) obj;  
// ... process host and port from address  
}  
if (obj instanceof LocalTransportAddress) {  
LocalTransportAddress address = (LocalTransportAddress) obj;  
// .... process local address, no host/port  
}

which is, I admit, still not pretty.

Note, if you have a node set to "local(true)", there is no host/port, but a  
LocalTransportAddress.
