protected boolean logMultipleExceptions() {
    return true;
  }
The first time a reply is received that contains an exception, the ReplyProcessor will save
that exception to be passed along to the waiting client thread. By default, any exception
encountered after that will be logged. Subclasses can reimplement this method to disable
logging of multiple exceptions.
