mvn javadoc:javadoc warnings

After running mvn clean install if mvn javadoc:javadoc is executed I'm seeing the following errors:

[INFO] --- maven-javadoc-plugin:3.3.1:javadoc (default-cli) @ jakarta.servlet.jsp.jstl ---
[INFO] Configuration changed, re-generating javadoc.

I don't understand what's causing this? One reported this as a JDK bug, but I use the latest version (Eclipse OpenJ9 VM 11.0.14.1) and still encountered it.

I don't see any harm coming out of this error. I think it's best to just work on this issue at a later time.
