Java News Roundup: GlassFish 8.0-M1, 2023 Highlights from Spring, BellSoft and WildFly

It was very quiet for the week of December 25th, 2023, but InfoQ found a few news items of interest that include: Eclipse GlassFish 8.0.0-M1, Apache Camel 3.22.0, Gradle 8.6-RC1, an updated draft specification for JEP 455, and retrospectives into the 2023 highlights from Spring, BellSoft and WildFly.


Aggelos Biboudis, principal member of technical staff at Oracle, has published an updated draft specification for JEP 455, Primitive types in Patterns, instanceof, and switch (Preview). This JEP, under the auspices of Project Amber and currently in Candidate status, proposes to enhance pattern matching by allowing primitive type patterns in all pattern contexts, and extend instanceof and switch to work with all primitive types.
