Running this on the CI machine triggers the same exception:

public class Main {

   public static void main(String[] args) throws Exception {
      InetAddress inet6Addresses = getInet6Addresses();
      System.out.println(inet6Addresses);
      DatagramSocket datagramSocket = new DatagramSocket(4242, inet6Addresses);
      datagramSocket.close();
   }

   private static InetAddress getInet6Addresses() throws Exception {
      for (Enumeration<NetworkInterface> en = NetworkInterface.getNetworkInterfaces(); en.hasMoreElements();) {
         NetworkInterface intf = en.nextElement();
         for (Enumeration<InetAddress> enumIpAddr = intf.getInetAddresses(); enumIpAddr.hasMoreElements();) {
            InetAddress addr = enumIpAddr.nextElement();
            if (addr instanceof Inet6Address) {
               return addr;
            }
         }
      }
      return null;
   }
