Facebook连接Java Smack 4

Question

通过这个例子，我试图让Facebook好友连接数量，但是我收到了错误

       XMPPConnection connection = new XMPPTCPConnection("chat.facebook.com");
       connection.connect();
       connection.login("asdd@asd.com", "pass");
       Roster roster = connection.getRoster();
       Collection<RosterEntry> entries = roster.getEntries();
       System.out.println(entries.size() + " buddy(ies):");

输出：

23,2014 2:23:04 PM org.jivesoftware.smack.filter.IQReplyFilter接受 警告：拒绝对IQ数据包的潜在欺骗性回复。过滤设置：packetId = JR6jj-0，to = null，local = null，server = chat.facebook.com。收到来自from = asdd @asd.com @ chat.facebook.com

的数据包

我使用的是Smack4.0.3版本
