This week's Java roundup for November 1st, 2021, features news from OpenJDK JEPs, JDK 18, Helidon 2.4.0, Open Liberty, point releases for Spring Cloud and its related subprojects, Quarkus 2.4.1.Final, Hibernate Reactive 1.0.1, WildFly 25.0.1 and JReleaser 0.8.0.


After its review had concluded, JEP 418, Internet-Address Resolution SPI, has been promoted from Proposed to Target to Targeted status for JDK 18. This JEP proposes to define a service-provider interface for host name and address resolution, so that the class may take advantage of resolvers other than the default built-in OpenJDK resolver.

JEP 421, Deprecate Finalization for Removal, has been promoted from Draft to Candidate status. This JEP deprecates the finalization mechanism, first introduced in JDK 1.0, for removal in a future JDK release. While finalization was designed to avoid resource leaks, it suffered several critical flaws such as unpredictable latency, uncontrolled behavior and threading, and was always enabled by default.

JDK 18

Build 22 of the JDK 18 early-access builds was made available this past week, featuring updates from Build 21 that include fixes to various issues. More details may be found in the release notes.

The feature set for JDK 18 currently stands as follows:

Developers are encouraged to report bugs via the Java Bug Database.

Microsoft Joins Java Community Process

As part of their continued commitment to the Java programming language, Microsoft has announced that they have signed the Java Specification Participation Agreement (JSPA) to join the Java Community Process (JCP). Heather VanCura, chair and director of the JCP program at Oracle, stated:

We are delighted to welcome Microsoft to the JCP program; it continues to represent the vibrant Java ecosystem. We look forward to seeing their contributions.

This news follows Microsoft's more recent contributions to the Java community as one of the founding members of the Adoptium Working Group and having introduced Microsoft Build of OpenJDK, their own downstream distribution of OpenJDK.

InfoQ will follow up with a more detailed news story.


Oracle has released Helidon 2.4.0 featuring: support for JDK 17 and the MicroProfile Long-Running Actions and Config specifications; integration with MicroStream 6.0; support for the Oracle Universal Connection Pool in native image builds; JEP 290 serialization filtering on incoming streams; and many more enhancements. More details may be found in the release notes.

Open Liberty

IBM has released Open Liberty with support for some features of the upcoming release of MicroProfile 5.0 to align with Jakarta EE 9.1.
