Update to Gradle 7.2

[anuraaga]

And try ubuntu-20.04.

@jkwatson I tried incorporating #3568 into this to see how it goes, mainly since I know it won't use the build cache at all.

Noticed a failure on this PR (caused by ubuntu? never saw it before but it seems like some random flakiness) where JUL is initialized within this security manager context, and JUL reads a property.

More smartness for managing these properties came to mind, for example a class that contains them as constants and by convention always add to that class. Didn't seem worth it for now though.

I want to merge this, but github isn't letting me change the branch protection rules to include the 20.04 entries. It let me do it yesterday, but it can't see the checks today. 🤔

[anuraaga]

@jkwatson Hmm can confirm I don't see them either. Manually editing the DOM in Chrome inspector didn't work either 😂

I wonder if merging this might force the issue. We can always manually merge after checking what's passed until that bug is fixed.

Yeah I had that thought to. Let's try it

@jkwatson I went ahead and removed the required status check on ubuntu-18.04. And now that can't be restored, searching in the checks only shows Build (macos-*). The GitHub bug appears to be something like only items that are already in the list are presented in the autocompletion...

[jkwatson]

Ugh. A little more work for us until that gets fixed. Has anyone logged it with github yet?
