More details may be found in the release notes and developers are encouraged to report bugs via the Java Bug Database.

OpenJDK has also released version 1.0 of Project Skara, a software configuration management and code review project containing numerous utilities for working with OpenJDK projects and their repositories. Building these utilities requires JDK 14 and Gradle 6.6.

JDK 18

Work on JDK 18 is already underway as the start of release updates has been declared with initial entries such as JDK-8267632 (Add source 18 and target 18 to javac) and JDK-8267631 (Add SourceVersion.RELEASE_18).

InfoQ has reported on Gluon and JavaFX activities related to the release of SceneBuilder 16 and an improved UI framework.

The Road to MicroProfile 4.1

The MicroProfile Working Group has released GraphQL 1.1.0. First released in February 2020, GraphQL is one of the four standalone APIs outside the umbrella of the MicroProfile core APIs. The intent of the MicroProfile GraphQL specification is to "provide a 'code-first' set of APIs that will enable users to quickly develop portable GraphQL-based applications in Java." This release is the first since the creation of the MicroProfile Working Group and the release of MicroProfile 4.0.

The Road to Quarkus 2.0

Red Hat has made release candidates, Quarkus 2.0.0.CR2 and Quarkus 2.0.0.CR3, available this past week featuring bug fixes that include a temporary workaround for integration issues related to a new annotation processor and IDEs. Red Hat promises to have a permanent solution implemented in the GA release scheduled for June 23, 2021.

Along with major changes in the SmallRye components and support for Vert.x 4.0 and MicroProfile 4.0, Quarkus 2.0 will feature a new continuous testing feature that provides continuous feedback during code changes. InfoQ recently spoke to Stuart Douglas, senior principal engineer at Red Hat, to discuss details of continuous testing.

Red Hat has also provided two maintenance releases in the Quarkus 1.13 release train, that is version 1.13.5.Final, featuring support for Maven 3.8.1, and version 1.13.6.Final introducing a regression in the Hibernate Validator extension due to an issue with Jandex, Red Hat's Java annotation indexer and offline reflection library.

The Road to Micronaut 3.0

Object Computing, Inc. has released the first milestone version of Micronaut 3.0 featuring improvements to Inversion of Control (IoC) items such as injection by generics, qualifier annotations and limiting injection types. Future milestone releases will feature a migration to the Jakarta Dependency Injection specification and Project Reactor as the default reactive library. More details may be found in the 3.0.0-M1 documentation.

Hibernate

Hibernate ORM 5.5.0.Final has been released featuring support for the Jakarta Persistence 3.0 specification. New artifacts using the -jakarta suffix (hibernate-core-jakarta, hibernate-envers-jakarta, hibernate-jpamodelgen-jakarta and hibernate-testing-jakarta) are now available on Maven Central.

Hibernate ORM is also certified as a compatible implementation for both the Jakarta Persistence 3.0 and Jakarta Persistence 2.2 specifications. Developers should include the hibernate-core-jakarta artifact for Jakarta Persistence 3.0 applications and the original hibernate-core artifact for Jakarta Persistence 2.2 applications. More details may be found in the what's new section of the website.

As a follow-up from last week, Hibernate Reactive 1.0.0.CR6 made available featuring a dependency upgrade to Hibernate ORM 5.5.0.Final, a dependency upgrade to Vert.x 4.1.0 and a fix related to the withSession() method not closing a session when an exception is thrown.

Payara

The June 2021 release of the Payara Platform includes Payara Community 5.2021.4 and Payara Enterprise 5.28.1. In addition to the usual bug fixes and component upgrades, Payara Community 5.2021.4 introduces a new AutoScale extension and a proof-of-concept Payara Kubernetes Operator.

Eclipse Vert.x

Eclipse has released Vert.x 4.1.0 featuring support for RxJava 3 and OpenTelemetry, and that Reactive Microsoft SQL Server Client has been added to the list of supported databases. Further details may be found in the what's new page.
