I was looking to update some code in jackson-module-scala for the M5 release and noticed that ChampHashMap and ChampHashSet had changed between M4 and M5.
I noticed that https://github.com/scala/scala/blob/2.13.x/src/library/scala/collection/immutable/ChampHashMap.scala now has its object and class called HashMap. Would it make sense to rename the scala file since the object and class have been renamed?
This would also apply to ChampHashSet.scala.
Yes, a pull request with that change would be welcome.
