   After some deep investigate, I found it's hard to do this with bytebuddy, 
   errors is open jdk9 
   ```
   Caused by: java.lang.ClassNotFoundException:

   ```
   according to the author, it is a bug related to 
[jdk](https://bugs.openjdk.java.net/browse/JDK-8145964) 
   I also test in open jdk11, there are some errors too.
   ```
