        List<GatewayTransportFilter> transportFilters, int socketBufferSize) throws IOException {

        // Set the receive buffer size before binding the socket so
        // that large buffers will be allocated on accepted sockets (see
        // java.net.ServerSocket.setReceiverBufferSize javadocs)
