title: Vaadin 7 + Spring Boot error page
body: <p>I have integrated Vaadin 7 and Spring Boot. Right now I need to implement error view in order to substitute standard page, for example:</p>
  
  <pre><code>Whitelabel Error Page
  
  This application has no explicit mapping for /error, so you are seeing this as a fallback.

  There was an unexpected error (type=Forbidden, status=403).
  Access is denied
  </code></pre>
  
  <p>It should be implemented as a separated Vaadin UI or in some other way ? Could you please provide me with an implementation of such page ? Thanks.</p>
