Github user mureinik commented on the issue: https://github.com/apache/commons-lang/pull/374 @britter I was half way through rewriting the `SystemDefaultsSwitch` as a JUnit Jupiter extension when I remembered your tweet from earlier this month and figured out that you already did this work in JUnit Pioneer. I hope I'm not stepping on any toes here, but if this conflicts with anything you had planned, I'd gladly abandon this PR.
