It is recommended to modify the ObjectTypeAdapter or allow to override the default implementation.
like this:
case NUMBER:

            String n = in.nextString();
            
            if (n.indexOf('.') == -1) {
                return Long.parseLong(n);
            }
            return Double.parseDouble(n);
