This week's Java roundup for November 1st, 2021, features news from OpenJDK JEPs, JDK 18, Helidon 2.4.0, Open Liberty 21.0.0.12-beta, 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.
OpenJDK
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 java.net.InetAddress 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:
- JEP 400: UTF-8 by Default
- JEP 408: Simple Web Server
- JEP 413: Code Snippets in Java API Documentation
- JEP 416: Reimplement Core Reflection with Method Handles
- JEP 417: Vector API (Third Incubator)
- JEP 418: Internet-Address Resolution SPI
Developers are encouraged to report bugs via the Java Bug Database.
