GraalVM
On the road to version 1.0, Oracle Labs has released version 0.9.24 of Native Build Tools, a GraalVM project consisting of plugins for interoperability with GraalVM Native Image. This latest release provides notable changes such as: support for Profile-Guided Optimization (PGO); migrate away from using ImageClassLoader in favor of ClassLoader for discovery of tests by JUnitPlatformFeature to eliminate the eager class initialization error during native image building time; and improved GraalVM installation instructions. Further details on this release may be found in the changelog.
Spring Framework
The first milestone release of Spring Cloud 2023.0.0-M1, codenamed Leyton, ships with: an implementation of Spring MVC and Jakarta Servlet; support for the Java HttpClient class; and milestone upgrades to sub-projects such as Spring Cloud Commons 4.1.0-M1 and Spring Cloud Task 3.1.0-M1. More details on this release may be found in the release notes.
The first release candidate of Spring Modulith 1.0.0 provides bug fixes, dependency upgrades and new features such as: avoid premature initialization of the SpringModulithRuntimeAutoConfiguration class to avoid a proxy warning; improve database interaction to mark event publications as completed; and allow the ApplicationModulesExporter class to write output to a file. Further details on this release may be found in the release notes. The GA release is scheduled to be announced at SpringOne at VMware Explore conference in late August 2023 and InfoQ will follow up with a more detailed news story.
Payara Cloud
Payara has announced a new 15-day free trial of their Payara Cloud cloud native runtime service for organizations considering their options for these kinds of services. Payara claims that use of Payara Cloud will shorten development cycles, improve operational efficiency and save money training developers in Kubernetes since Payara Cloud handles Kubernetes in the background.
Quarkus
Red Hat has released version 3.2.4.Final of Quarkus with notable changes such as: documentation of Maven configuration options that may be relevant when running tests; a fix for the @RouteFilter annotation that stopped working with WebSocket requests using Quarkus 3.2.0.Final; and a fix for the OpenTelemetry (OTEL) SDK autoconfiguration ignores the OTEL service name in favor of the Quarkus application name. More details on this release may be found in the changelog.
MicroProfile
On the road to MicroProfile 6.1, the MicroProfile Working Group has provided the first release candidate of the MicroProfile Telemetry 1.1 specification featuring notable changes such as: a clarification of which API classes must be available to users; an implementation of tests that is not timestamp dependent; and a clarification of the behavior of the Span and Baggage beans when the current span or baggage changes. Further details on this release may be found in the list of issues.
OpenXava
The release of OpenXava 7.1.4 features dependency upgrades and notable fixes such as: use of the @DisplaySize annotation with a value greater than 50 is ignored when used with @Column(length=255); files lost when uploading several files at same time on creating a new entity; and moving columns to customize a list does not work if the application name contains underscores. More details on this release may be found in the release notes.
Foojay.io
The Foojay.io community calendar now has the ability to automatically import individual Meetup pages maintained by Java Users Groups. This eliminates the need for JUGs to manually enter their Meetup events on the Foojay.io calendar. To get started, JUG leaders would need to register on the Foojay.io Slack channel and specify either daily or weekly basis for automatic updates.
JVM Language Summit
Sharat Chander, senior director, Java and Container Native Product Management and Developer Relations at Oracle, provided InfoQ with a summary of the 2023 JVM Language Summit that featured this agenda and OpenJDK Committers' Workshop.
Last week represented the 15th edition of the JVM Language Summit. Taking place in Santa Clara, California, this three-day summit hosted by Oracle's Java language and JVM teams offered an open technical collaboration among language designers, compiler writers, tool builders, runtime engineers, and VM architects.
The summit welcomed the creators of both the JVM and programming languages for the JVM to share their experiences. It also included non-JVM developers of similar technologies to attend or speak on their runtime, VM, or language of choice. The attendee mix comprised participants from 15 companies, 30 countries, as well as 11 members of the Java Champions luminary program and 16 Java User Group leaders and organizers.
From sessions exploring dimensions from Project Leyden, Loom, Panama and Valhalla, the summit also offered insight into areas such as Generational ZGC, the Class-File API preview feature, and more.
Chander stated that "session recordings will be made available soon so keep an eye out for an update!"
