I want to convert map to Java bean, like this

public static <T> T convert(Map<String, Object> values, Class<T> beanClass) throws Exception {
    T instance = beanClass.getConstructor().newInstance();

    Map<String, Field> fieldMap = Stream.of(beanClass.getDeclaredFields())
        .peek(field -> field.setAccessible(true))
        .collect(Collectors.toMap(Field::getName, field -> field));

    values.forEach((key, value) -> {
      try {
        fieldMap.get(key).set(instance, value);
      } catch (IllegalAccessException e) {
        throw new RuntimeException(e);
      }
    });

    return instance;
  }

How can I optimize away Java reflection with byte buddy?
