NullPointer for service constructor

I'm trying to constuct a service implimentation that receives references to a couple of other services that registers the objects into a super class. But I get a null pointer exception.

What am I doing wrong here?

public class AppModule {

public static void bind(ServiceBinder binder) {
// bind low-level services and utilities
binder.bind(CommonsEmailNotificationSender.class); // implements NotificationSender to send email
binder.bind(TextMarketerNotificationSender.class); // implements NotificationSender to send sms

...
// bind facades
...
binder.bind(NotificationSenderFacade.class, DefaultNotificationSenderFacade.class); // combines the NotificationSender instances above

public interface NotificationSender {

boolean sendNotification(String toUsername, String fromUsername, String replyto, String to, String messageText, boolean admin);

boolean sendNotificationLater(String toUsername, String fromUsername, String replyto, String to, String messageText, boolean admin);

public interface NotificationSenderFacade {

NotificationSender getNotificationSender(String classnme);

boolean sendNotification(String toUsername, String fromUsername, List<NotificationRouting>routes, String messageText, boolean admin);

boolean sendNotificationLater(String toUsername, String fromUsername, List<NotificationRouting>routes, String messageText, boolean admin);

public abstract class AbstractNotificationSenderFacade implements NotificationSenderFacade {

/**
* The log.
*/
@Inject
private Logger log;

private Map<String, NotificationSender> notificationSenders
= new HashMap<String, NotificationSender>();

// put the notification senders into a map during subclass construction
protected void registerNotificationSender(NotificationSender notificationSender) {
String classname = notificationSender.getClass().getSimpleName();
notificationSenders.put(classname, notificationSender);
log.info("registered " + classname);

@EagerLoad
public class DefaultNotificationSenderFacade extends AbstractNotificationSenderFacade {

/**
* The log.
*/
@Inject
private Logger log;

/**
* Create the facade for the given the notification senders.

* @param emailNotificationSender
* @param smsNotificationSender
*/
public DefaultNotificationSenderFacade(CommonsEmailNotificationSender emailNotificationSender,
TextMarketerNotificationSender smsNotificationSender) {
super();
super.registerNotificationSender(emailNotificationSender);
super.registerNotificationSender(smsNotificationSender);
log.debug("registered notification senders");

@Override
public boolean sendNotification(String toUsername, String fromUsername, List<NotificationRouting> routes, String messageText, boolean admin) {
boolean success = true;
for (NotificationRouting route : routes) {
if (route.getTo().contains("@")) {
boolean done = super.getNotificationSender("CommonsEmailNotificationSender")
.sendNotification(toUsername, fromUsername, route.getReplyto(), route.getTo(), messageText, admin);
