OptionHelper.java

  118         try {
  119             args = CommandLine.parse(args); // Detect @file and load it as a command line.
  120         } catch (java.io.IOException e) {
  121             Log.warn("Problem reading @file: "+e.getMessage());
  122             return;
  123         }

If you can't read the @-file, that should be an error, not a warning.
