Add failing tests around subclasses

[daniel-beck]

I was so confused earlier today trying to mark something @Restricted, and apparently, this is the cause.

[timja]

shall we merge @daniel-beck?

This PR adds failing tests, your CI setup is broken:

ah k,

I thought that

access-modifier-checker/src/it/extend-override/invoker.properties

invoker.buildResult = failure

was telling it that it expected to fail and would be removed when fixing the issue

[timja]

Issue is this: jenkins-infra/pipeline-library#139 (comment)

[basil]

Needs the Invoker equivalent of @Ignore pending a fix for the bug.
