Java News Roundup: Jakarta Data and Jakarta NoSQL Milestones, Class-File API Targeted for JDK 23

Bookmarks

This week's Java roundup for March 25th, 2024, features news highlighting: JEP 466, Class-File API (Second Preview), targeted for JDK 23; milestone releases of Jakarta Data and Jakarta NoSQL specifications; the second release candidate for JobRunr 7.0.0; and point releases for Spring projects, Quarkus, Helidon and LangChain4j.

OpenJDK

After its review has concluded, JEP 466, Class-File API (Second Preview), has been promoted from Proposed to Target to Targeted for JDK 23. This JEP proposes a second round of preview to obtain feedback from the previous round of preview: JEP 457, Class-File API (Preview), delivered in JDK 22. This feature provides an API for parsing, generating, and transforming Java class files. This will initially serve as an internal replacement for ASM, the Java bytecode manipulation and analysis framework, in the JDK with plans to have it opened as a public API. Goetz has characterized ASM as "an old codebase with plenty of legacy baggage" and provided background information on how this draft will evolve and ultimately replace ASM.

JDK 23

Build 16 of the JDK 23 early-access builds was made available this past week featuring updates from Build 15 that include fixes for various issues. Further details on this release may be found in the release notes.

Jakarta EE

The fourth milestone release of the Jakarta Data 1.0.0 specification features notable changes such as: removal of the countBy() method from the BasicRepository interface as it was a magical method name query and considered awkward; replace Sort<T> by Sort<? super T> where appropriate to allow sorting by a member of a super entity; and a new method, elements(), added to the inner Cursor interface, defined in the PageRequest interface, that automatically packages elements as an unmodifiable list. More details on this release may be found in the changelog.

Similarly, the first milestone release of Jakarta NoSQL 1.0.0 specification features notable changes such as: removal of the Document, Key-Value and Column Family APIs as they are now maintained in Jakarta Data; and the addition of new annotations, @MappedSuperclass, @Embeddable, @Inheritance, @DiscriminatorColumn and @DiscriminatorValue for improved support of NoSQL databases. More details on this release may be found in the changelog.
