Review Comment:
Thanks for rephrasing your initial comment for me. This reinforces my
understanding.
> so that spotlessApply doesn't produce different formatting results
depending on the JDK version it is executed with.
I totally agree this wouldn't be acceptable! Do you maybe remember under
what circumstances this can be observed?
In this PR I modified the CI scripts so that `./gradlew -DallVersions build
-x test -x javadoc -x integrationTest` runs with java 11-21 and all runs agree
on the desired formatting. While I can see that formatting depends on GJF
version, I don't see it being dependent on the JDK version it is executed with.
> Since we release for JDK8, we need to use the GJF version that works with
JDK8.
I hear you on this, but would appreciate helping me understanding the why. I
still fail to see it.
Is it because we expect Iceberg contributors to locally run JDK 8? I am
concerned that JDK 8 is unsupported, unmaintained publicly and potentially not
safe to run, so would prefer not to force contributors to use it, even though
the **releases** target Java 8 compatibility.
