สอบถามค่ะเกี่ยวกับ java core

Java 9
(api breaking changes)
Module java.xml.ws.annotation
    javax.annotation.Generated
==>
Module java.compiler
    javax.annotation.processing.Generated

Package javax.annotation.processing
https://docs.oracle.com/javase/10/docs/api/javax/annotation/processing/package-summary.html

Fix: properly detect the @Generated annotation on JDK9 to avoid package splits
