This week's Java roundup for November 20th, 2023, features news from OpenJDK, JDK 22, JCON World 2023, and point, milestone and GA releases for: Spring Boot, Spring Framework, Spring Security, Spring Authorization Server, Spring GraphQL, Spring Integration, Spring Session, Spring Vault, Quarkus, Hibernate ORM, Hibernate Search, Infinispan, JHipster, JBang, OpenXava, Testcontainers and Gradle.
OpenJDK
After its review has concluded, JEP 447, Statements before super(...) (Preview), has been promoted from Proposed to Target to Targeted for JDK 22. This JEP, under the auspices of Project Amber, proposes to: allow statements that do not reference an instance being created to appear before the this() or super() calls in a constructor; and preserve existing safety and initialization guarantees for constructors. Gavin Bierman, consulting member of technical staff at Oracle, has provided an initial specification of this JEP for the Java community to review and provide feedback.
JEP 461, Stream Gatherers (Preview), has been promoted from Candidate to Proposed to Target for JDK 22. This JEP proposes to enhance the Stream API to support custom intermediate operations. "This will allow stream pipelines to transform data in ways that are not easily achievable with the existing built-in intermediate operations." More details on this JEP may be found in the original design document written by Viktor Klang, software architect, Java Platform Group at Oracle. The review is expected to conclude on November 29, 2023.
JEP 462, Structured Concurrency (Second Preview), has been promoted from Candidate to Proposed to Target for JDK 22. This JEP will propose to re-preview the API in JDK 22, without change, in order to gain more feedback from the previous round of preview: JEP 453, Structured Concurrency (Preview), delivered in JDK 21. This feature simplifies concurrent programming by introducing 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 review is expected to conclude on December 1, 2023.
JEP 458, Launch Multi-File Source-Code Programs, has been promoted from Candidate to Proposed to Target for JDK 22. This JEP proposes to enhance the Java Launcher to execute an application supplied as one or more files of Java source code. This allows a more gradual transition from small applications to larger ones by postponing a full-blown project setup. The review is expected to conclude on December 1, 2023.
JDK 22
Build 25 of the JDK 22 early-access builds was made available this past week featuring updates from Build 24 that include fixes to various issues. Further details on this build may be found in the release notes.
