  <p>As I understand this exception there is something wrong with my module setup, but I am not clear what I need to change:</p>
  
  <ul>
  <li>Add additional modules to <code>--add-modules</code> and which?</li>
  <li>Add <code>--add-opens</code> to the command with which modules</li>
  <li>Something completely different?</li>
  </ul>
