AddServer

Hey,

how can I add a server via Plugin?
This code does not work.

Code (Text):

 public static void addServers(String name,int port, int count) throws SQLException {
        int x = 1;
        while (x <= count) {
            if (!BungeeCord.getInstance().getServers().containsKey((name + x).toUpperCase())) {
                ServerInfo info = ProxyServer.getInstance().constructServerInfo((name + x).toUpperCase(), InetSocketAddress.createUnresolved("127.0.0.1", (port + x)), "MOTD", false);
                ProxyServer.getInstance().getServers().put((name + x).toUpperCase(), info);
            }
            x++;
        }
    }
