例 

import java.net.Inet6Address;
import java.net.InetAddress;
import java.net.UnknownHostException;

public class Authentication {

  public static void main(String[] args) throws UnknownHostException {
    boolean found = false;
    InetAddress[] addrs = Inet6Address.getAllByName("www.juliasoft.com");
    for (InetAddress addr: addrs) {
      if (addr.getCanonicalHostName().equals("231.13.35.1"))       // "Hostname in Condition (Java)" warning issued here 
        found = true;
      else if ("112.34.5.103".equals(addr.getCanonicalHostName())) // "Hostname in Condition (Java)" warning issued here 
        found = true;

      found |= addr.getCanonicalHostName().startsWith("131.");     // "Hostname in Condition (Java)" warning issued here 
    }

    if (found)
      System.out.println("OK");
  }
}

解決法

Check if the warning actually corresponds to a real security issue related to authentication and, if that is the case, use a more secure authentication procedure.
