This feature simplifies concurrent programming by introducing the concept of structured concurrency to " treat groups of related tasks running in different threads as a single unit of work, thereby streamlining error handling and cancellation, improving reliability, and enhancing observability." The only significant change is the addition of a method to the StructuredTaskScope.Joiner interface, that allows for implementations of that interface to return a result after the timeout expires.

One of the biggest annoyances of Java has always been the amount of code needed to write even "Hello World." This is a barrier for new users. Oracle wants to do something about this. "Paving the on-ramp" is therefore receiving a lot of attention, including in the pre-briefing we attended on Java 25. A good example of this is JEP 512 (Compact Source Files and Instance Main Methods). New users can write their first programs without needing extensive knowledge of the language.
