> BaseRequestItem.getTypesParameter() calls BeanJsonConverter.convertToObject().
> but if no exists json parameter, means getParameter(parameterName) returns null, 
> it happens null point exception.
> and the method can't handled NPE. (it can control JSONException)
>   public <T> T getTypedParameter(String parameterName, Class<T> dataTypeClass) {
>     try {
>       return converter.convertToObject(getParameter(parameterName), dataTypeClass);
