/**
 * 17.6.2.6 Never
 * <p/>
 * The Container invokes an enterprise Bean method whose transaction attribute
 * is set to Never without a transaction context defined by the EJB spec.
 * <p/>
 * The client is required to call without a transaction context.
 * <p/>
 * If the client calls with a transaction context, the Container throws:<ul>
 * <li>java.rmi.RemoteException exception if the client is a remote client</li>
 * <li>javax.ejb.EJBException if the client is a local client</li> </ul>
 * <p/>
 * If the client calls without a transaction context, the Container performs the
 * same steps as described in the NotSupported case.
