我试图在JellyBean设备上加载我的Json到我的类时遇到异常 stackoverflow错误，但在ICS上它完全没问题，这是一个错误吗？

JSON 

{
  "user": {

     "id": 216,
     "city_id": 30910,
     "city_name": "Edinburgh",
     "country_id": 482,
     "country_name": "United Kingdom",
     "email": "q@q.com",
     "username": "q@q.com",

                }
            ]
        }
    ]
}

}

我的班级 

public class User implements Serializable, Cloneable{

public String plain_password="";

public ArrayList<Category> categories;

@Override
public User clone() throws CloneNotSupportedException {
    return (User)super.clone();
  }
}

public class Category {

}

public class SubCategory {
public int id;
public String name;
public boolean isChecked;
public boolean isChanged;

public boolean equalCategory(SubCategory mCategory) {
    return id == mCategory.id;
}
 }

方式 

public void getCurrentUser(final AuthToken token, final LoadCompleteListener listener) {
    if (listener != null) {
        new Thread(new Runnable() {

            @Override
            public void run() {
                try {
                    URL url = new  URL(mURL_API.concat(SysUtilHelper.getDeviceLanguage() + "/user?token=" + token.token));
                    HttpURLConnection conn = (HttpURLConnection) url.openConnection();
                    conn.setRequestProperty("Connection", "close");
                    conn.connect();
                    if (getResponseCode(conn) == HttpURLConnection.HTTP_OK) {
                        BufferedReader in = new BufferedReader(new InputStreamReader(conn.getInputStream()));
                        JsonObject request = (JsonObject) mJparser.parse(in.readLine());
                        in.close();
                        if (!request.has("error")) {

                            User user = mGson.fromJson(request.getAsJsonObject("user"), new TypeToken<User>() {
                            }.getType());
                            listener.onLoadSucces(user);
                        } else {
                            listener.onLoadError(request.get("message").toString());
                        }
                        conn.disconnect();
                    } else {
                        int responseCode = conn.getResponseCode();
                        conn.disconnect();
                        throw new NetworkException(ERROR_BAD_REQUEST + responseCode);
                    }
                } catch (Exception e) {
                    e.printStackTrace();
                    listener.onLoadError(e.toString());
                }

            }
        }).start();

    }
}

P.S。我正在使用gson 2.2.4

我认为BufferedReader中的问题

 {
        InputStream is = conn.getInputStream();
        InputStreamReader isr = new InputStreamReader(is,"UTF8");
        BufferedReader br=new BufferedReader(isr);
        String read;
        StringBuffer sb = new StringBuffer();
        while((read = br.readLine()) != null) {
            sb.append(read);
        }
        br.close();
        sb.toString();

}

还尝试使用fromJson（JsonObject，User.class）函数
