我认为这是非常重要的提及我在尝试使用facebook4j运行代码时遇到了相同的异常。

我花了很多时间试图弄清楚，而且我很困难。

代码测试类：

import com.restfb.DefaultFacebookClient; 
import com.restfb.FacebookClient; 
import com.restfb.Version; 
import com.restfb.types.User; 

public class Test { 

    public Test() { 
    } 

    public static void main(String[] args) { 

     String accessToken = "******"; 

     FacebookClient fc = new DefaultFacebookClient(accessToken, Version.UNVERSIONED); // Setting version has no effect 

     User me = fc.fetchObject("me", User.class); 

     System.out.println(me.getFirstName()); 
     System.out.println(me.getLanguages()); 
    } 

}

好吧，我试图运行不同的机器上的代码，它出来，有与开发环境的设置的问题。
