This week's Java roundup for April 15th, 2024, features news highlighting: the second milestone release of Jakarta EE 11; Stream Gathers (Second Preview) and Vector API (Eighth Incubator) targeted for JDK 23; the first release candidate of Spring Boot 3.3.0; the first alpha release of Hibernate 7.0.0; and the fifth milestone release of GlassFish 8.0.0.
OpenJDK
After its review had concluded, JEP 473, Stream Gatherers (Second Preview), was promoted from Proposed to Target to Targeted for JDK 23. This JEP proposes a second round of preview from the previous round, namely: JEP 461, Stream Gatherers (Preview), delivered in JDK 22. This will allow additional time for feedback and more experience with this feature with no user-facing changes over JEP 461. This feature was designed to enhance the Stream API to support custom intermediate operations that 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 and this InfoQ news story.
Similarly, JEP 469, Vector API (Eighth Incubator), has also been promoted from Proposed to Target to Targeted for JDK 23. This JEP incorporates enhancements in response to feedback from the previous seven rounds of incubation: JEP 460, Vector API (Seventh Incubator), delivered in JDK 22; JEP 448, Vector API (Sixth Incubator), delivered in JDK 21; JEP 438, Vector API (Fifth Incubator), delivered in JDK 20; JEP 426, Vector API (Fourth Incubator), delivered in JDK 19; JEP 417, Vector API (Third Incubator), delivered in JDK 18; JEP 414, Vector API (Second Incubator), delivered in JDK 17; and JEP 338, Vector API (Incubator), delivered as an incubator module in JDK 16. Originally slated to be a re-incubation by reusing the original Incubator status, it was decided to keep enumerating. The Vector API will continue to incubate until the necessary features of Project Valhalla become available as preview features. At that time, the Vector API team will adapt the Vector API and its implementation to use them, and will promote the Vector API from Incubation to Preview.
JEP 476, Module Import Declarations (Preview), has been promoted from its JEP Draft 8315129 to Candidate status. This preview feature proposes to enhance the Java programming language with the ability to succinctly import all of the packages exported by a module with a goal to simplify the reuse of modular libraries without requiring to import code to be in a module itself.
George Adams, senior software engineering manager at Microsoft, and Bruno Borges, principal PM manager at Microsoft, have submitted JEP Draft 8330623, Remove Windows 32-bit x86 Port, that proposes to fully remove the Windows 32-bit x86 port following its deprecation as described in JEP 449, Deprecate the Windows 32-bit x86 Port for Removal, delivered in JDK 21. The goals are to: remove all code paths in the code base that apply only to Windows 32-bit; cease all testing and development efforts targeting the Windows 32-bit platform; and simplify OpenJDK's build and test infrastructure, aligning with current computing standards.
