`excludePackageNames` with latest `maven-javadoc-plugin` not working correctly

[mechite]

Affected version

3.12.0

Bug description

It used to (and still in the documentation) accept wildcards with "subpackages":

<excludePackageNames>org.example.*</excludePackageNames>

When running with my local GraalVM 21 installation, this works.
Running with my local GraalVM 25 installation, it does not exclude anything (not even org.example!)
Same issues occur with Oracle JDK 25.

Combined with:

• <doclint>all,-missing</doclint>
• <failOnError>true</failOnError>
  ...this is causing a build of mine to fail.

Yes, I will migrate to directly specify each package, as I do also believe subpackages may not be a good convention.
I am unsure if this issue belongs to this Maven plugin.

A quick check shows:

-exclude pkglist
Unconditionally, excludes the specified packages and their subpackages...
Java 25 documentation for javadoc tool
...so perhaps it does not belong here.

However, a quick skim read - it does not appear this documentation mentions wildcards.
The plugin.xml of maven-javadoc-plugin does:

Wildcards work as followed:

• a wildcard at the beginning should match one or more directories
• any other wildcard must match exactly one directory

Example: <excludePackageNames>.internal:org.acme.exclude1.:org.acme.exclude2</excludePackageNames>
(and I was previously using these wildcards in a project).
