Play-Framework: nicht registrieren Klasse in Ebean Server

Question

ich von Java 6 bis 7 Alles zu aktualisieren versuche funktioniert in Java 6. Aber wenn ich Java 7 verwenden, gibt spielen folgende Fehler

Cannot register class [models.ActivityMetrics] in Ebean server 
In conf/dev.conf at line 43. 
41 
42 evolutionplugin=disabled 
43 ebean.default = "models.*" <<<<<<<<<<<<<<<<<<<<< 
44 

Es ist Maven-Projekt. Es baut erfolgreich auf, aber gibt den obigen Fehler zur Laufzeit an.

Ich benutze Spiel 2.2.0.

Ich versuchte mit clean, compile, play Sequenz von Befehlen in Antwort auf eine ähnliche Frage in der Vergangenheit empfohlen, aber es hat nicht geholfen.

Ändern sich die Anforderungen für Modelle, wenn Java 7 anstelle von Java 6 verwendet wird? Irgendeine Empfehlung für was soll ich ändern.

Update:

den folgenden Stack-Trace in der Protokolldatei gefunden.

Fehler wurde nach der Verwendung von Getter anstatt auf die Felder direkt gegangen Below Änderungen gearbeitet.

Thread https://groups.google.com/forum/#!topic/play-framework/eWFwZ75T6wk geholfen, die Antwort zu finden.

 public void delete() throws Exception { 
-  String query = "DELETE FROM " + this.activity.merchant + "_activity_metrics WHERE uuid = ?"; 
+  String merchant = this.getActivity().getMerchant(); 
+  String query = "DELETE FROM " + merchant + "_activity_metrics WHERE uuid = ?"; 
     System.out.println(query); 
-  System.out.println(this.activity.uuid); 
+  System.out.println(this.getActivity().getUuid());
