Thema: "Why don't they just...?! The Deliberations Behind Evolving Java"

There are many nifty features that Java could have but doesn't.
Why, though, how hard can it be to implement them?
Why don't they just...

• let us add fields to records?
• add `?.` for null-safe member selection?
• add extension methods?
• remove the need for semicolons?
• introduce immutable collections?
• make `Stream` handle exceptions?
• turn `Optional` into a proper monad?

After this talk, you'll know.
And have gained insight into the deliberations behind the decisions that evolve Java and why nothing can "just" be implemented.
