Further details on this release may be found in the release notes. The second milestone release of Spring Cloud 2023.0.0, codenamed Leyton, ships with: a migration of all Spring Cloud project documentation to Antora, a multi-repository documentation site generator and milestone upgrades to sub-projects such as Spring Cloud Commons 4.1.0-M2, Spring Cloud Starter Build 2023.0.0-M2 and Spring Cloud Kubernetes 3.1.0-M2. With most of the features under the Project Panama early-access builds having moved over to incubating JEPs, jextract, a tool that mechanically generates Java bindings from a native library headers, remains the only feature and will therefore be maintained in its own project.

With this build, developers running on MacOS Catalina or higher will be required to remove the quarantine attribute from the bits before using the jextract binaries. Project Jextractīuild 21-jextract+1-2 of the Project Jextract early-access builds was made available to the Java community and is based on JDK 21. Ondro Mihályi, director at OmniFish, has been working on virtual thread support for GlassFish and has provided this working example. More details on this release may be found in the release notes. Eclipse GlassFishĮclipse GlassFish 7.0.9, the ninth maintenance release, features component updates and notable fixes such as: an IllegalArgumentException attempting to deploy an application with an EJB remote interfaces to Embedded GlassFish the contextInitialized() method defined in the ServletContextListener interface is invoked multiple times when deployed and the stop-local-instance command line parameter doesn't stop the instance of the server. Further details on this build may be found in the release notes.įor JDK 22, developers are encouraged to report bugs via the Java Bug Database. JDK 22īuild 17 of the JDK 22 early-access builds was made available this past week featuring updates from Build 16 that include fixes to various issues. More details on JEP 430 may be found in this InfoQ news story. This JEP enhances the Java programming language with string templates, string literals containing embedded expressions, that are interpreted at runtime where the embedded expressions are evaluated and verified. Jim Laskey, software development director at Oracle Corporation, has submitted JEP Draft 8314219, String Templates, to finalize this feature from its previous round of preview, JEP 430, String Templates (Preview), delivered in JDK 21.

This JEP proposes to 'enhance pattern matching by allowing primitive type patterns to be used in all pattern contexts, align the semantics of primitive type patterns with instanceof, and extend switch to allow primitive constants as case labels.' JEP 455, Primitive types in Patterns, instanceof, and switch (Preview), has been promoted from its Draft 8288476 to Candidate status. This 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 _. JEP 456, Unnamed Variables and Patterns, has been promoted from its Draft 8311828 to Candidate status to finalize this feature from its previous round of preview: JEP 443, Unnamed Patterns and Variables (Preview), delivered in JDK 21.

Brian Goetz, Java language architect at Oracle, characterized ASM as 'an old codebase with plenty of legacy baggage' and provided background information on how this draft will evolve and ultimately replace ASM. This will initially serve as an internal replacement for ASM, the Java bytecode manipulation and analysis framework, in the JDK with plans to have it opened as a public API. This JEP proposes to provide an API for parsing, generating, and transforming Java class files.

JEP 457, Class-File API (Preview), has been promoted from its Draft 8280389 to Candidate status.
