OpenJDK
JEP Draft 8285724, Deprecate JMX M-Lets (Management Applets) for Removal, a feature JEP, proposes to deprecate the Java Management eXtension (JMX) "M-Let" feature for removal in a future release as it has become obsolete and irrelevant for modern application development. The removal of M-Lets, originally inspired by applets, and the javax.management.loading API will have no effect on JMX and its related technologies.
JDK 19

Spring Framework
Spring Shell 2.1.0 has been released featuring: a new interface, CommandRegistration, as a new way to programmatic define commands; an overhaul of the Spring Shell internals for initial support for the upcoming GA releases of Spring Framework 6.0 and Spring Boot 3.0; and a reevaluation of the @ShellMethod and @ShellOption annotations such that new annotations may be necessary to better align with the CommandRegistration interface. Further details on this release may be found in the release notes.
Spring Cloud OpenFeign 3.0.8 has been made available as a bugfix and documentation release that backports fixes from the 3.1.x release train. The most notable backport is related to the cascading deserialisation in the Page interface from Spring Data.

Version 1.0 will be based on Spring Security 6.0 and Spring Framework 6.0 and will require a minimal version of JDK 17, Tomcat 10 and Jetty 11. The team will also release a version 0.4.0 to support the Spring Security 5.x release train and JDK 8. More details on what developers can expect between now and November 2022 may be found in the release schedule and list of features. InfoQ will follow up with a more detailed news story.
Helidon
Two years since the release of Helidon 2.0, Oracle has released Helidon 3.0 that ships with: JDK 17 as a minimal version; an implementation of MicroProfile 5.0 and selected Jakarta EE 9.1 specifications.; support for JEP 290, Filter Incoming Serialization Data, such that deserialization is disabled by default; an updated Helidon SE routing API; a new project starter; and an updated CLI. Further details on this release may be found in the release notes. InfoQ will follow up with a more detailed news story.
GraalVM
Oracle Labs has released GraalVM 22.2 featuring: a smaller GraalVM JDK distribution that is more modular and no longer includes the JavaScript runtime, the LLVM runtime, or VisualVM; improvements in the use of Native Image with third party libraries, smaller memory footprint and heap dumps; faster startup and extended library support for GraalPython; and improved interoperability in GraalJS. GraalVM 22.2 ships with JDK 11 and JDK 17 builds. More details on this release may be found in this YouTube video. InfoQ will follow up with a more detailed news story.
Quarkus
Red Hat has released Quarkus 2.11.1.Final and 2.10.4.Final. Both versions address CVE-2022-2466, a vulnerability discovered in the SmallRye GraphQL server extension in which server requests were not properly terminated. As explained in the blog post:
Unfortunately, the previous fix introduced in 2.10.3.Final and the non-released 2.11.0.Final was incomplete and the issue was still present in another form.
Other new features include: new Redis Client API; dependency upgrades to Vert.x 4.3.2 and Netty 4.1.78; a change in GraphQL endpoints to be a Singleton by default; and a default to JDK 17-based builder images for native executable generation.

Eclipse Vert.x
With the upcoming release of JDK 19 that will support virtual threads, the Vert.x team has created a virtual threads incubator project for developers to experiment with virtual threads and provide feedback as necessary. The incubator project currently contains an implementation of async/await based on a proof of concept by August Nagro, software engineer at Axoni. This project is meant to provide central community experiments with virtual threads and can, therefore, host any other virtual thread-based project.
Jakarta EE 10
