JEP 453: Structured Concurrency (Preview): Simplifies concurrent programming by introducing an API for structured concurrency, which can help promote a type of concurrent programming that could eliminate typical pitfalls arising from cancellation and shutdown – which include thread leaks and cancellation delays – and increases the observability of concurrent code.
This allows builders streamline and increase the dependability in their assignments by creating the Java language far more semantic to ensure intricate information-oriented queries is usually expressed concisely and securely.
