JAVA.INSEC.HIC : Hostname in Condition (Java)

JavaScript is not currently enabled, but is required for full CodeSonar manual search and browse functionality.

If you are viewing this file in your hub's Web GUI, enable JavaScript in your browser: you will also need it for GUI functionality.

If you opened this file directly from disk, your browser may be directly suppressing JavaScript functionality: certain browsers perform this suppression on local files (but not files delivered by web servers) for security reasons.

If you access the manual through the hub's Web GUI, the functionality will not be suppressed because the hub is a web server.
Alternatively, your browser may allow you to explicitly disable the security setting that suppresses functionality. See the CodeSonar FAQ for more information.

    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");
  }
}
