Gson 2.2.2仅在4.2.1上引起stackoverflow

Question

我正在开发一个Android应用程序,它使用JSON字符串从服务器下载兴趣点.一切都工作正常但是因为我已经开始测试4.2.1,我收到了以下错误:

奇怪的是,它在我试过的每个其他版本上都能正常工作......

这是我认为它崩溃的线:

    Gson g = new Gson();
    JSONResponse jsonResponse = g.fromJson(serverReply, JSONResponse.class); <---

和我想要创建的类:

/**
 * The JSONResponse from the server
 * @author Tom
 *
 */
public class JSONResponse {
    private String          status;
    private PointOfInterest result;

    /**
     * Creates a JSONResponse object 
     * @param json
     * @return
     */
    static JSONResponse convertJSONToResponse(String json){
        Gson gson = new Gson();
        JSONResponse jsonResponse = gson.fromJson(json, JSONResponse.class);
        return jsonResponse;
    }

    /**
     * Get Point of Interest
     */

    public PointOfInterest getPointofInterest(){
        return result;
    }

    public String getStatus(){
        return status;
    }

    /**
     * Get PrivateSection, area we can put our own data
     */
    /*
    public String getPrivateSection(){
        return privateSection;
    }
    */
    /**
     * Creates a JSONResponse object 
     * @param json
     * @return
     */
    String convertJSONResponseToJSON(){
        Gson gson = new Gson();
        return gson.toJson(this);
    }
}

请注意我知道我在这里使用的糟糕的设计模式,这个应用程序适用于我在大学学习的移动应用程序课程,所以请放轻松!

编辑 结果将降级gson降级为1.7.1对我有用.

Answer 1

所以事实证明这是一个错误,因为Erik Nedwidek指出.我采取了简单的路线并将gson从2.2.2降级到1.7.1,现在一切都很有效!
