Can I use a non-injected field in the constructor of a stateless EJB?

Is it Java EE compliant to have an empty constructor in a stateless EJB using a non-injected field as in the example? 

@WebService
@Stateless
@SOAPBinding(...)
@RunAs(...)
public class ParameterWebservice {

   @EJB
   private PService pService;

   private final Set<PrivacyO> allowed;

   public ParameterWebservice() {
      allowed= new HashSet<>();
      allowed.add(PrivacyO.EXPOSE_THROUGH_LAYER_A);
      allowed.add(PrivacyO.EXPOSE_THROUGH_LAYER_B);
   }

   ...
}
