I have basically two classes:

```
@Entity 
class A {
   @Load
   Ref<B> other;

   public B getOther() {
      return other.get();
   }
}

@Entity
class B {
   ...
}

```

When I call someInstanceOfA.getOther() it throws:

```
java.lang.ClassCastException: com.google.appengine.api.datastore.Entity cannot be cast to objectify.example.B

```

I'm using objectify v 4.0b3.

Thanks!
