@MBaesken @zzambers I've updated this patch which should cover the config issue as pointed out by @zzambers. The latest version throws `SkippedException` with a hint should the match fail. Done in https://github.com/openjdk/jdk/pull/19530/commits/0e52e004e9766301294743aa42c8306d7a25a34f and added this info to the bug as well.

Good to go now?
