@MikeThomsen I would maybe put a comment in the `src/test/java/.gitignore`
file explaining why it's there so someone in the future doesn't see it as a
superfluous tooling artifact and remove it, and then your test is silently no
longer executed and we don't catch regressions. We've had similar occurrences
in some of the other modules. ---
