Why use an AtomicReference here? I wanted to make a general type I could reuse in gradle-jdks to configure the versions/distributions, which would involve modifying extension objects in the regular gradle style. So we use an AtomicReference here just to make it act like a box you can store data in.

I would hope to reuse this in gradle-jdks to have everything be ETE lazy.

perhaps move to the extensions package and make package private?

It might have been easier to set this as just a single function you have to replace - but I'm concerned that just leads to everything becoming confusing if you "override" the value in custom gradle for example to test a new JDK major version that hasn't been fully released yet.

This is basically making it fully lazy.

Before this PR
You must know about all the JDK versions you need to set before the baseline-java-versions plugin uses them. This can make being a lazy as possible harder, and complicates the logic slightly.
