This week’s Java roundup for March 20th, 2023 features news from OpenJDK, JDK 20, JDK 21, Amazon Corretto 20, BellSoft Liberica JDK 20, multiple Spring milestone and point releases, Quarkus 3.0.0.Beta1 and 2.16.5, Helidon 3.2.0, Open Liberty 23.0.0.3-beta, Micronaut 4.0.0-M1, Camel Quarkus 3.0.0-M1, JBang 0.105.1, Failsafe 3.3.1, Maven 3.9.1 and Gradle 8.1-RC1.

OpenJDK

JEP 431, Sequenced Collections, has been promoted from Proposed to Target to Targeted status for JDK 21. This JEP proposes to introduce “a new family of interfaces that represent the concept of a collection whose elements are arranged in a well-defined sequence or ordering, as a structural property of the collection.” Motivation was due to a lack of a well-defined ordering and uniform set of operations within the Collections Framework. More details on JEP 431 may be found in this InfoQ news story.

JEP 443, Unnamed Patterns and Variables (Preview), was promoted from JEP Draft 8294349 to Candidate status this past week. This preview JEP proposes to “enhance the language with unnamed patterns, which match a record component without stating the component’s name or type, and unnamed variables, which can be initialized but not used.” Both of these are denoted by the underscore character as in r instanceof _(int x, int y) and r instanceof _.

JDK 20

Oracle has released version 20 of the Java programming language and virtual machine, which ships with a final feature set of seven JEPs. More details may be found in this InfoQ news story.
