  All exceptions are directed to this page, by the server configuration
  See <error-page> tag in the /WEB-INF/web.xml file.

  Some exceptions are fowarded to other pages to be able to
  display a more appropriate error message.

  Only severe, unexpected exceptions, are handled by this page,
  which will only display a stack trace!
