Maybe the change should include toLowerCase(Locale.ENGLISH) as it could break depending on the system locale?

Or Locale.ROOT? A quick "find usages" in my IDE finds many similar case-insensitive checks around HTTP are using it.

Question: is using a stub the preferred way of testing an abstract class? The Spock docs mention using a partial mock using Spy, but from a quick search through the project code, I don't see Spy used anywhere.

Yes, in general we don't use Spy.
