more specifically the use of

<http://miningmadness.com|miningmadness.com>

That change is if the reverse lookup results in

<http://miningmadness.com|miningmadness.com>

, ignore it and try use the original address. Java uses reverse lookups when resolving the local address (used to get the bound port with HTTPS), and that address being mapped to localhost is just stupid, but was causing tests to fail on Windows trying to access the real site instead of localhost and the certificate does not match. That fix is saying, if the address ever resolves to that site, don't use it!

that address is mapped to localhost? 😕

This is just of Windows on GitHub action agents

I see, cool, thanks for the explanation 🙂
