> The annotation
[`@PreDestroy`](https://docs.oracle.com/javaee/7/api/javax/annotation/PreDestroy.html)
doesn't have the annotation
[`@Inherited`](https://docs.oracle.com/en/java/javase/11/docs/api/java.base/java/lang/annotation/Inherited.html),
so the inheritance does not work. I will undo this change.
Perhaps the behavior is different depending on the implementation. When
tested in `spring` or `quarkus`, it works by inheriting `@PreDestroy` of the
parent class.
