@laeubi Do you think I could have caused this test failure on Windows?

I also don't understand why mac is failing. It says Error: Could not find satisfied version for SemVer '8'.

[laeubi]

The Windows Test is a flapping test and the mac currently lacks a suitable java 8 JVM I'm currently looking into that here:

• Drop old java versions from the github builds #3785

[tivervac]

@laeubi In that case, seems like this MR is ready :D

Do you want to squash the changes or should I merge the individual commits?

Do you want to squash the changes or should I merge the individual commits?

I'd like to keep the three separate commits
