FacebookConnectionFactory connection GET request for "https://graph.facebook.com/me" resulted in 400 (Bad Request) MissingAuthorizationException:

I am trying to develop an app for Facebook. I wrote a facebook controller and created connectionFactory object, got the oAuth oprations and accessgrant object. I got the access token also But Once I try to create a connection

Connection<Facebook> connection = connectionFactory.createConnection(accessGrant); 

I am getting the error :

MissingAuthorizationException: Authorization is required for the operation, but the API binding was created without authorization.

Please let me know what is wrong here? Is the instantiation is not correct for connectionFactory object.
