The road to Jakarta EE 11 included four milestone releases with the potential for release candidates as necessary before the GA release in 3Q2024.
BellSoft
BellSoft has released versions 24.0.2 for JDK 22, 23.1.4 for JDK 21 and 23.0.5 for JDK 17 of their Liberica Native Image Kit builds as part of the Oracle Critical Patch Update for July 2024 to address several CVEs and bugs.
Spring Framework
The release of Spring Cloud Data Flow 2.11.4 primarily addresses: CVE-2024-37084, Remote Code Execution in Spring Cloud Data Flow, a vulnerability where an attacker, who has access to the Skipper Server API, can use a crafted upload request to write an arbitrary file to any location on the file system which could lead to compromising the server; and PRISMA-2023-0067, where an attacker can send a specially-crafted request to take advantage of an improper input validation by the StreamReadContraints class causing a denial of service. Other improvements include: the ability for a user to specify the application version when creating a schedule; and a new endpoint, /tasks/thinexecutions, for more efficient retrieval of task executions pages without all the extra detail. Further details on this release may be found in the release notes.
Version 4.24.0 of Spring Tools 4.24.0 has been released with notable changes such as: support for Spring Expression Language (SpEL) syntax highlighting and validation inside Java and embedded Spring Data queries; syntax highlighting and validation for MySQL and PostgreSQL queries; and support for bean name code completion and navigation for name attribute of the Jakarta Annotations @Resource annotation. More details on this release may be found in the release notes.
WildFly
The release of WildFly 33 delivers bug fixes, component upgrades and new features such as: an enhanced overriding of base configuration settings using a YAML file by using the YAML file to add unmanaged deployments to the configuration; the core-management subsystem now allows developers to enable scanning of deployments for usage of classes/methods in the SmallRye and Hibernate ORM libraries annotated with @Experimental and @Incubating, respectively; and utilities to reload a server to a different stability level in the testsuite. Further details on this release may be found in the release notes. InfoQ will follow up with a more detailed news story.

Arquillian
The release of Arquillian 1.9.1.Final provides dependency upgrades and notable changes such as: replace use of the Java ThreadLocal class with the Java Hashtable class due to a memory leak in Arquillian Warp; support for the @ArquillianResource annotation parameter injection on methods annotated with @Deployment; and a resolution to integration test build issue to ensure that versions get updated. Further details on this release may be found in the changelog.
Jox
As a follow-up from the release of Jox 0.3.0, as described in the July 15, 2024, Java news roundup, details related to their new structured concurrency module were made available by Adam Warski, chief R&D officer at SoftwareMill, who told InfoQ:
We've added a "programmer-friendly" API for structured concurrency. This blog describes it in detail, and contrasts it with what's proposed by the structured concurrency JEP.
Introduced to the Java community in February 2024, Jox is a new virtual threads library that implements an efficient Channel data structure in Java designed to be used with virtual threads.
