Consider replacing Guava Lists.newArrayList (and similar) usage?

[sleberknight]

For unmodifiable lists, sets, and maps, should we use Java's factory methods that were added in JDK 9 (collection factory methods)?

This would include replacing Lists.newArrayList() with List.of() and Sets.newHashSet() with Set.of().

Obviously, if the list or set isn't unmodifiable (i.e. elements are added after construction) then we can't make this change (without other design changes). In those cases, I'd recommend we stick with the Guava factory methods since you can "one-liner" create them with elements.

I'm on board with this change. We should use native APIs as much as possible.
