Gson. Deserialize integers as integers and not as doubles

Question

I have json object with arbitary values inside. And I want to deserialize it in a Map. Everything is ok except converting integers to a doubles. See example:

Answer 1

It's my code

private static class MapDeserializer implements JsonDeserializer> {
    public Map deserialize(JsonElement json, Type typeOfT, JsonDeserializationContext context)  throws JsonParseException {
        Map m  = new LinkedHashMap();
        JsonObject jo = json.getAsJsonObject();
        for (Entry  mx : jo.entrySet()){
            String key = mx.getKey();
            JsonElement v = mx.getValue();
            if(v.isJsonArray()){
                m.put(key, g.fromJson(v, List.class));
            }else if(v.isJsonPrimitive()){
                 Number num = null;
                  try {
                      num = NumberFormat.getInstance().parse(v.getAsString());
                  } catch (Exception e) {
                      e.printStackTrace();
                  }
                m.put(key,num);
            }else if(v.isJsonObject()){
                m.put(key,g.fromJson(v, Map.class));    
            }

        }
      return m;
   }
}

private static class ListDeserializer implements JsonDeserializer> {
    public List
