Thanks for putting this together, @marcphilipp.

I reviewed the PR in the browser and made some suggestions for minor improvements regarding Javadoc.

Regarding the implementation, that also looks good (at least as far as I can tell within the browser), and the new tests reflect what I'd expect. 👍

Thanks for making the previous changes!

I've requested two minor Javadoc changes.
