Dear All,


We are pleased to announce the status of Java 27 features for Eclipse 2026-09 (4.41).


JEP 532: Primitive Types in Patterns, instanceof, and switch (Fifth Preview)


The compiler and the basic IDE support for the above JEP is  available via the release which can be obtained through one of the following ways:


        1. Java 27 Marketplace entry:  https://marketplace.eclipse.org/content/java-27-support-eclipse-2026-09-441

        2. Update site :  https://download.eclipse.org/jdt/updates/4.41-P-builds/



Additionally, we will have the following options available soon:


        3. Eclipse Installer: https://www.eclipse.org/downloads/packages/installer

        4. From a 4.42 integration build: https://download.eclipse.org/eclipse/downloads/


Known issues will be tracked via the issue list and will be retargeted to 4.42 timeframe or to the next Java version as appropriate.


I would also like to take this opportunity to thank everyone – the team, contributors, bug reporters, early adopters, and one and all - involved in Java 27 support. And to those who took care of non-Java 27 support related activities to keep the master as well as the next Java version tree move forward which was a first. In short, this release, like always, can be attributed to the open communication and excellent teamwork. Thanks to all again!



Thanks and Regards,

Manoj N Palat
