/**

 * @param bindAddress an InetAddress indicating the bounded network interface to determine whether
 *        the service port is available or not.
 * @param port an integer indicating the network port to listen for client network requests.
 * @throws BindException if the network address and port are not available. Address defaults to
 *         localhost (or all network interfaces on the local system) if null.
