No case conversion occurs as part of these tests. Is this failure reproducible? Are bits of memory randomly being flipped as we succumb to the slow, silent entropy of the universe?

Hopefully @MattGal the machine name didn’t change? If not what is it now.

@parose1 can confirm but in my experience, they do not change the machine name. That’s why all our Macs still have their Jenkins names 😃

Let’s meet back here in 2 months and see whether this test failed again and if so on which machine.
