This week's Java roundup for April 7th, 2025, features news highlighting: milestone releases of Spring AI 1.0 and Spring Cloud 2025; beta releases of Open Liberty 2025.0.0, Hibernate Reactive 3.0 and LangChain4j 1.0; and the sixth release candidate of Vert.x 5.0.
JDK 25
Build 18 of the JDK 25 early-access builds was made available this past week featuring updates from Build 17 that include fixes for various issues. More details on this release may be found in the release notes.
For JDK 25, developers are encouraged to report bugs via the Java Bug Database.
Jakarta EE
In his weekly Hashtag Jakarta EE blog, Ivar Grimstad, Jakarta EE developer advocate at the Eclipse Foundation, provided an update on Jakarta EE 11 and Jakarta EE 12, writing:
We are getting closer and closer to finalizing the refactoring of the Jakarta EE Platform TCK. The goal right now is to have the Jakarta EE 11 Platform ready for release review by the end of May 2025. Stay tuned for updates.
Plan reviews for Jakarta EE 12 are going on as we speak. Check out the progress in the Jakarta EE 12 Plan Review status board. My guess is that we will see quite a few more coming forward as the April 15 deadline is fast approaching.
The road to Jakarta EE 11 included four milestone releases, the release of the Core Profile in December 2024, the release of Web Profile in April 2025, and a fifth milestone and first release candidate of the Platform before its anticipated release in 2Q 2025.
Spring Framework
The seventh milestone release of Spring AI 1.0.0 features several breaking changes that align with the structural improvements to "create a more modular and maintainable codebase while reducing unnecessary dependencies in your applications." Core architecture improvements include: a comprehensive modular architecture; modular autoconfiguration; package reorganization; and framework enhancements. This will be the last milestone release as the team plans a release candidate and the GA release in time for the Spring I/O conference in May 2025.
The third milestone release of Spring Cloud 2025.0.0, codenamed Northfields, features bug fixes and notable updates to sub-projects: Spring Cloud Kubernetes 3.3.0-M3; Spring Cloud Function 4.3.0-M2; Spring Cloud Stream 4.3.0-M3; and Spring Cloud Circuit Breaker 3.3.0-M3. This release is based upon Spring Boot 3.5.0-M3. More details on this release may be found in the release notes.
Versions 4.3.0-M3, 4.2.1, 4.1.6, 4.0.10 and 3.1.10 of Spring Cloud Config have been released to address CVE-2025-22232, a vulnerability where, under certain conditions, the Spring Cloud Config server may not use the Spring Cloud Vault token sent by clients using a X-CONFIG-TOKEN header.

The release of WildFly 36 delivers notable features such as: support for MicroProfile 7.0; experimental support to launch WildFly from JBang; improvements to the WildFly AI Feature Pack; support for the Prometheus Registry in the micrometer extension; and enhancements to the WildFly documentation page. More details on this release may be found in the release notes.
Open Liberty
IBM has released version 25.0.0.4-beta of Open Liberty featuring support for JDK 24; a file-based health check mechanism with MicroProfile Health as an alternative to the traditional /health endpoints; and InstantOn support for the J2EE Management 1.1, Application Client Support for Server 1.0, Jakarta Application Client Support for Server 2.0 and Web Security Service 1.1 features.
Hibernate

Eclipse Vert.x

The team anticipates the GA release to be available in May 2025. More details on this release may be found in the release notes and list of deprecations and breaking changes.
