This week's Java roundup for September 23th, 2024, features news highlighting: the proposed release schedule for JDK 24; JEP 475, Late Barrier Expansion for G1, promoted from Candidate to Proposed to Target for JDK 24; JEP 486, Permanently Disable the Security Manager, promoted from its JEP Draft 8338625 to Candidate status; and Quarkus joining the Commonhaus Foundation.
OpenJDK
JEP 475, Late Barrier Expansion for G1, was promoted from Candidate to Proposed to Target for JDK 24. This JEP proposes to simplify the implementation of the G1 garbage collector's barriers, which record information about application memory accesses, by shifting their expansion from early in the C2 JIT's compilation pipeline to later. The goal is to reduce the execution time of C2 when using the G1 collector. The review is expected to conclude on October 2, 2024.
JEP 486, Permanently Disable the Security Manager, has been promoted from its JEP Draft 8338625 to Candidate status. This JEP proposes to permanently disable the SecurityManager class since it was deprecated with JEP 411, Deprecate the Security Manager for Removal, delivered in JDK 17. While it was possible for developers to still enable the SecurityManager class while it has been deprecated, this functionality will be removed as the next step for ultimate removal.
JDK 24
Build 17 of the JDK 24 early-access builds was made available this past week featuring updates from Build 16 that include fixes for various issues. More details on this release may be found in the release notes.
Mark Reinhold, chief architect, Java Platform Group at Oracle, formally proposed the release schedule for JDK 24 as follows:
- Rampdown Phase One (fork from main line): December 5, 2024
- Rampdown Phase Two: January 16, 2025
- Initial Release Candidate: February 6, 2025
- Final Release Candidate: February 20, 2025
- General Availability: March 18, 2025
The review period for this proposed schedule is expected to conclude on October 2, 2024.
For JDK 24, developers are encouraged to report bugs via the Java Bug Database.
Spring Framework
Versions 3.4.0-M2, 3.3.3 and 3.2.8 of Spring Shell have been released featuring support for JEP 454, Foreign Function & Memory API, delivered in JDK 22, via JLine, the Java library for handling console input. These releases build on Spring Boot versions 3.4.0-M3, 3.3.4 and 3.2.10, respectively. Further details on these releases may be found in the release notes for version 3.4.0-M2, version 3.3.3 and version 3.2.8.
Quarkus
Red Hat has released version 3.15 of Quarkus, a new long-term support release provides dependency upgrades and resolutions to notable issues such as: a class loading failure from the findFunctions() method defined in the AzureFunctionsProcessor class; and a bidirectional streaming failure in the Dev UI console. The Quarkus team has stated that new features will be delivered in Quarkus 3.16, scheduled for the end of October 2024. More details on this release may be found in the release notes.
Open Liberty
IBM has released version 24.0.0.10-beta of Open Liberty featuring: beta support for JDK 23; and improved handling of SameSite cookies by allowing SameSite=None on incompatible clients. Details on how to set a SameSite cookie with Open Liberty may be found on this website.
WildFly
The first beta release of WildFly 34 delivers bug fixes, dependency upgrades and enhancements such as: a relocation of dependency JARs from the OpenTelemetry module to their own respective modules to minimize the size of the OpenTelemetry module; and a simplification of installing singleton service for a deployment that was once very cumbersome. Further details on this release may be found in the release notes.
Apache Software Foundation
Maintaining alignment with Quarkus, the release of Camel Quarkus 3.15.0, composed of Camel 4.8.0 and Quarkus 3.15.0, provides resolutions to notable issues such as: a deprecation of the Kotlin and Kotlin DSL extensions because they only provide a Kotlin function wrapper around the configure() method defined in the RouteBuilder abstract class; and a ClassNotFoundException from the SmallRye FallbackFunction class due to Quarkus having upgraded to SmallRye 6.4.0. More details on this release may be found in the release notes.
LangChain4j
Version 0.35.0 of LangChain for Java (LangChain4j) features new integrations: chat and embedding models from GitHub Models; document loader from Google Cloud Storage; scoring model from Google Vertex AI Ranking API; scoring model from ONNX Reranker; embedding store from Tablestore; and embedding and scoring models from Voyage AI. Other notable changes include: support for embedding models, the ability to count tokens and enumerated structured outputs from Google AI; and support for observability in Ollama. Further details on this release may be found in the release notes.
JBang
Version 0.119.0 of JBang provides bug fixes and a new feature in which junctions can now be created on WindowsOS that resolves an issue where executing the jbang jdk default {version} command would fail. More details on this release may be found in the release notes.
Java Operator SDK
The release of Java Operator SDK 4.9.5 features bug fixes and some refactoring that includes: change the package access of the asBoolean() method, defined in the BooleanWithUndefined enum, to public; a rename and deprecation of the defaultNonSSAResource() method, defined in the ConfigurationService interface, to defaultNonSSAResources(); and change the shouldUseSSA() method, also defined in the ConfigurationService interface, to use types as opposed to instances and corresponding tests. Further details on this release may be found in the release notes.
Commonhaus Foundation
The Commonhaus Foundation, a new non-profit organization dedicated to the sustainability of open source libraries and frameworks, has announced that Quarkus has joined the foundation this past week. In a blog post published in late July 2024, Max Rydahl Andersen, distinguished engineer at Red Hat, described their transition to the foundation, writing:
Quarkus will continue to innovate and evolve. We are dedicated to making Quarkus the best framework for Java development. This transition will enable us to welcome more contributions from a diverse range of developers and organisations. We are actively working on upcoming releases and are eager to hear your ideas and feedback.
They join notable projects such as: Hibernate, JReleaser, JBang, OpenRewrite, SDKMAN, EasyMock, Objenesis and Feign.
Introduced to the Java community at Devnexus in April 2024, the foundation provides succession planning and fiscal support for self-governing open-source projects.
RefactorFirst
Jim Bethancourt, principal software consultant at Improving, an IT services firm offering training, consulting, recruiting, and project services, has released version 0.5.0 of RefactorFirst, a utility that prioritizes the parts of an application that should be refactored. This release delivers: support for JDK 21; performance improvements on large codebases with a high number of commits; and the addition of a simple HTML resort that may be used in GitHub Actions. More details on this release may be found in the release notes.
Gradle
Gradle 8.10.2, the second maintenance release, ships with resolutions to notable issues: a failure to update the Gradle wrapper in version 8.10.1; a failure using a build with the Kotlin Mutliplatform plugin and a reused daemon; and the configureEach(Action) method, defined in the DefaultTaskCollection class, on a task set cannot be executed in the current context. Further details on this release may be found in the release notes.
