I am developing an app for android which downloads points of interest from a server using JSON strings. Everything was working fine but since I have started testing on 4.2.1, I have been getting the following error:

The weird thing is, it works fine on every other version I have tried…

Here is the line I think it is crashing at:

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

and the class I am trying to create:

/**
 * 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);
    }
}

Please note I am aware of the terrible design pattern I have employed here, this application is for a mobile apps class I am taking in college so take it easy on me !

Edit
Turns out downgrading gson to 1.7.1 works for me.

    So it turns out this is a bug as Erik Nedwidek pointed out. I took the easy route and downgraded gson from 2.2.2 to 1.7.1, everything works a treat now !
