If I reference a session bean from another bean or an MDB, when deployed to JBoss 4.0.4 GA - I get a NullPointerException when it tries to deploy the MDB where the session bean is referenced. The error when JBoss starts up is:

--- MBeans waiting for other MBeans ---
ObjectName: jboss.j2ee:jar=EJB3Test.jar,name=MyMDBImpl ,service=EJB3
State: FAILED
Reason: java.lang.NullPointerException



@Consumer(activationConfig =
{
@ActivationConfigProperty(propertyName="destinationType", propertyValue="javax.jms.Queue"),
@ActivationConfigProperty(propertyName="destination", propertyValue="queue/test"),
@ActivationConfigProperty(propertyName="MaxPoolSize", propertyValue="1")
})
public class MyMDBImpl implements MyMDB {
@EJB MySessionBean myBean;
public void callBeanMethod() {
myBean.sayHello();
}
}

If I take out the @EJB reference and the call to the bean's method, of course it deploys fine, as nothing really happens. Did I miss something in terms of understanding how @EJB references can be used?
