InternetAddress.lookup produce an error on web

[alihabbash]

I use the method InternetAddress.lookup from the ConnectionStatusHandler.checkConnection method on the web and it's producing an unimplemented error
and it happens both when I have and when I don't have internet connection
here is the full log:

I have exactly the same problem, not working on web.
