docs: Notification that an error occurred when we were expecting to receive
  a response. This method is used to "wake up" any conversations using
  a connection for which an error occurres. At the point this method is
  invoked, the connection will already have been marked "invalid".
  <p>
  It is used to notify
  the per conversation receive listener of (almost) all error conditions
  encountered on the associated connection.
