title: Play Framework - dev server shutting down after refreshing
body: <p>My problem is that every time I run <code>sbt run</code>, the server works until I refresh the page. After that, I get this in my terminal</p>
  
  <pre><code>Uncaught error from thread [play-dev-mode-akka.actor.default-dispatcher-3]: javax/xml/bind/DatatypeConverter, shutting down JVM since 'akka.jvm-exit-on-fatal-error' is enabled for for ActorSystem[play-dev-mode]
  java.lang.NoClassDefFoundError: javax/xml/bind/DatatypeConverter
  </code></pre>
  
  <p>Since there's not much ressources about play and scala on the web, I really need guidance for this.</p>
