From iris.clark at oracle.com Thu May 1 18:52:21 2025 From: iris.clark at oracle.com (Iris Clark) Date: Thu, 1 May 2025 18:52:21 +0000 Subject: JSR 400 (Java SE 25): JEP Proposed to Target: 505: Structured Concurrency (Fifth Preview) Message-ID: The following JEP with scope "SE" has been proposed to target JDK 25: 505: Structured Concurrency (Fifth Preview) https://openjdk.org/jeps/505 Summary: Simplify concurrent programming by introducing an API for structured concurrency. Structured concurrency treats groups of related tasks running in different threads as single units of work, thereby streamlining error handling and cancellation, improving reliability, and enhancing observability. This is a preview API. The announced deadline for feedback to jdk-dev is Thu 8 May 21:00 UTC: https://mail.openjdk.org/pipermail/jdk-dev/2025-May/010027.html If there are no unresolved objections at that time, then the JEP will be moved to the Targeted state, indicating that the feature is expected to appear in the specified release of the JDK Project. For more information about states, see the JEP Process document: https://openjdk.org/jeps/1 A dashboard that lists JEPs with "SE" scope may be found via a link on this page: https://openjdk.org/projects/jdk/25/spec/ Thanks, Iris From iris.clark at oracle.com Fri May 2 16:54:14 2025 From: iris.clark at oracle.com (Iris Clark) Date: Fri, 2 May 2025 16:54:14 +0000 Subject: New candidate JEP: 517: HTTP/3 for the HTTP Client API Message-ID: The following JEP with scope "SE" has been moved to the Candidate state: 517: HTTP/3 for the HTTP Client API https://openjdk.org/jeps/517 Summary: Update the HTTP Client API to support the HTTP/3 protocol, so that libraries and applications can interact with HTTP/3 servers with minimal code change. A JEP in the Candidate state is a feature deemed worthy of consideration by the JDK Project, but with no commitment to deliver the feature in any particular release of the JDK Project. Later, the JEP may be moved to the Targeted state, which indicates that the feature is expected to appear in a specific release of the JDK Project. For more information about states, see the JEP Process document: https://openjdk.org/jeps/1 A JEP with "SE" scope that reaches the Targeted state will be listed in the Specification of the Java SE Platform JSR which corresponds to the targeted JDK Project release.

Scoped values are easier to reason about than thread-local variables. They also have lower space and time costs, especially when used together with virtual threads (JEP 444) and structured concurrency (JEP 505).

The Scope of JEP 509 is "JDK", not "SE"; hence there is no impact on SE APIs. Thanks to everyone who was quick to notice and report my error!
