Fixed version (ground truth):

    return null;

    isAlist=true;
    Type genericType=field.getGenericType();
    if (!(genericType instanceof ParameterizedType)) {
      return null;
    }
    Type listType=((ParameterizedType)genericType).getActualTypeArguments()[0];
    if (ParameterizedType.class.isAssignableFrom(listType.getClass())) {
      listType=((ParameterizedType)listType).getRawType();
    }
    if (listType instanceof Class) {

        return null;
