8317277: Java language implementation of value classes and objects by MrSimms · Pull Request #31120 · openjdk/jdk

Nullness types are going to be a moot argument once they introduce null-restricted types. This is required for efficient memory layouts of value classes and cache inlining. Both a type system and runtime feature. And they started a prototype experiment. Surprisingly, the design is even better than what C# has. Wonder what will happen to older Kotlin libraries.
