      Description

      Consider the following code with the specs quoted

              URLConnection c = new URL("file:/usr").openConnection();
              c.connect();

              System.out.println("c = " + c);
              // "The Map keys are Strings that represent the response-header field names"
              System.out.println(c.getHeaderFields().keySet());

              // Returns the key for the nth header field.
              // It returns null if there are fewer than n+1 fields.
              System.out.println(c.getHeaderFieldKey(0));

              // "It returns null if there are fewer than n+1 fields."
              System.out.println(c.getHeaderField(0));

      The output would be:

      c = sun.net.www.protocol.file.FileURLConnection:file:/usr
      []
      content-type
      text/plain

      ::getHeaderFields indicates that there are zero header fields while getHeaderField/Key(index) say the opposite

      FtpURLConnection seem to be affected as well as FileURLConnection
