报错如上所示，也是刚接触smack不久

代码也是那种最基础的demo的代码，但是不知道为什么会出现这样的问题，用这段代码可以给Royee Messageer客户端发消息，但是一旦接收消息就会报上面的错误，不知道怎么解决~~（smack版本是最新发布的版本4.1.3,码完这些发现已经发布4.1.4了。。）

Chat newchat=chatmanager.createChat(targetaccount,new ChatMessageListener() {

@Override
public void processMessage(Chat arg0, Message message) {
System.out.println("Message from "+message.getFrom()+":"+message.getBody());
}
});
@SuppressWarnings("resource")
Scanner scanner=new Scanner(System.in);
while(true){
String outmessage=scanner.nextLine();
try {
newchat.sendMessage(outmessage);
} catch (NotConnectedException e) {
e.printStackTrace();
}
}
