 /**
  * XmppLoginHandler handles authentication handshake for XmppConnection. It
  * receives incoming data using onDataReceived(), calls |sendMessageCallback|
  * to send outgoing messages and calls |onHandshakeDoneCallback| after
  * authentication is finished successfully or |onErrorCallback| on error.
  *
  * See RFC3920 for description of XMPP and authentication handshake.
  *
  * @param {string} server Domain name of the server we are connecting to.
  * @param {string} username Username.
  * @param {string} authToken OAuth2 token.
  * @param {boolean} needHandshakeBeforeTls Set to true when <starttls> handshake
  *     is required before starting TLS. Otherwise TLS can be started right away.
  * @param {function(string):void} sendMessageCallback Callback to call to send
  *     a message.
  * @param {function():void} startTlsCallback Callback to call to start TLS on
  *     the underlying socket.
  * @param {function(string, remoting.XmppStreamParser):void}
  *     onHandshakeDoneCallback Callback to call after authentication is
  *     completed successfully
- * @param {function(remoting.Error, string):void} onErrorCallback Callback to
+ * @param {function(!remoting.Error, string):void} onErrorCallback Callback to
  *     call on error. Can be called at any point during lifetime of connection.
