Unable to send mail using notifications_sendEmail() method

[GoogleCodeExporter]

Hello all,

I am using the facebook-java-api-3.0.0-SNAPSHOT API for my facebook 
application. 

To send mail i am using the below specified code snippet.

-----------
some code here 
-----

            String sessionKey = "<SESSION_KEY>";
            String apiKey = "<API_KEY>";

            String secretKey = "<SECRET_KEY>";

            try {
                FacebookJaxbRestClient client = new 
FacebookJaxbRestClient(apiKey, secretKey, sessionKey);
                boolean appUser = client.users_isAppUser();
                Long userId = 
client.users_getLoggedInUser();
                client.friends_get(uid);
                FriendsGetResponse friendsResp = 
(FriendsGetResponse) client.getResponsePOJO();
                List<Long> friends = friendsResp.getUid();

                Collection<Long> frndList = new 
ArrayList<Long>();

                for (Iterator iterator = 
friends.iterator(); iterator.hasNext();) {
                    Long element = (Long) 
iterator.next();
                    frndList.add(element);
                }
                List<Long> name = 
client.notifications_sendEmail(frndList, "Test email ... ", "test 
mail....", "test mailsss...");
                System.out.println("Email sent to .... ");  
                for (Iterator iterator = name.iterator(); 
iterator.hasNext();) {
                        Long element = (Long) 
iterator.next();

System.out.println(element);
                    }

                } catch (FacebookException e) {
                System.err.println(e.getMessage());
                e.printStackTrace();
            }

--------

But my trace shows a class cast exception from the line 

List<Long> name = client.notifications_sendEmail(frndList, "Test email ... 
", "test mail....", "test mailsss...");

The trace details are as follows...
