> `java.util.concurrent.ConcurrentHashMap` is relatively old and has not been updated to reflect the current state of Java and can be modernized:
>
> * Add `@Serial` annotations
> * Seal classes and restrict subclassing for internal classes
> * Use pattern matching for instance
> * Remove redundant modifiers (such as some final declarations)
> * Use Objects.requireNonNull for invariant checking
> * Use diamond operators instead of explicit types
> * Simplify expressions using Math::max
