Hi @tehnodev,

Congratulations on raising your first issue for the Spring Framework! 👍

This turns out to be the same underlying issue raised in #29505 which will later be automatically handled by the fix for spring-io/spring-asciidoctor-backends#68.

However, I'll go ahead and address the issues in core-beans.adoc since I don't know when we'll be able to upgrade to spring-asciidoctor-backends 0.0.4.
