jdepend-maven-plugin not working anymore due to LinkageError

Not sure if it is the correct Jira project ..... but:

Running the site build with Maven 3.9.9 on my example project yields the following error and leaves me without jdependency-maven-plugin report (everything worked fine with site 3.12.x) and the following message:
