Gson stackoverflow onJson .... CLUELESS

我收到此错误但没有任何意义......

这是保存gson的代码：

        Gson gson = new Gson();
        String json = gson.toJson(new Pais("a",null));
        try {
            FileWriter writer = new FileWriter(c.getApplicationInfo().dataDir+File.separatorChar+"datos.json");
            writer.write(json);
            writer.close();
            System.out.println(json);
        } catch (IOException e) {
            e.printStackTrace();
        }

这是Pais课程：

public class Pais  {
    public String nombre;
    public Drawable bandera;

    public Pais(String n,Drawable b){
        this.nombre=n;
        this.bandera=b;
    }
    public String getNombre() {
        return nombre;
    }
    public void setNombre(String nombre) {
        this.nombre = nombre;
    }


    public Drawable getBandera() {
    return bandera;
}
public void setBandera(Drawable bandera) {
    this.bandera = bandera;
}
@Override
public boolean equals(Object other){
    return (((Pais)other).nombre.equals(this.nombre));
}   
  }

我不理解错误，因为它没有循环或任何东西......我是否在课堂上注释？

谢谢！ 何。
