Take a look at the com.liferay.trash.taglib.servlet.taglib.UndoTag class and its following method:

 

private Map<String, Object> _getData() {
   ThemeDisplay themeDisplay = (ThemeDisplay)request.getAttribute(
      WebKeys.THEME_DISPLAY);

   PortletRequest portletRequest = (PortletRequest)request.getAttribute(
      JavaConstants.JAVAX_PORTLET_REQUEST);

   PortletDisplay portletDisplay = themeDisplay.getPortletDisplay();

   String key =
      portletDisplay.getId() +
         SessionMessages.KEY_SUFFIX_DELETE_SUCCESS_DATA;

   if (!SessionMessages.contains(portletRequest, key)) {
      return null;
   }

   return (HashMap<String, Object>)SessionMessages.get(
      portletRequest, key);
}

You get CCE in the return statement if something different from HashMap accessible by the key.

I've faced with it when passed Collections.singletonMap to BaseMVCActionCommand.addDeleteSuccessData.
