      The bug

      Should DNS names be validated to be correct, then remove incorrect characters? Or at least strip whitespace on either side?

      How to reproduce

      Connect to " x.nerd.nu", you'll get an error about the server not being found.

      Potential fix

      Easy way to fix in java:

      String servername; //assuming we're storing the info from the "Server Address" box into a string
      servername = servername.trim();
