We’re pleased to announce the availability of Eclipse OpenJ9 v0.58.0 which adds support for OpenJDK 26 🎉 A big thanks to IBM for building and distributing Semeru Runtimes Open Edition with this release. Downloads available here: ibm.biz/GetSemeru

Great to see the IntelliJ IDE supporting #java developers using @IBM Semeru Runtimes with the @openj9 JVM!!

Three talks you should not miss, and I am honoured and grateful to have participated in one of them alongside @MarkusKett !

Why are people already discussing #JCON2026 & #JCON USA? Because #JCON2025 set new standards: cinema + code, #GenAI, mentoring, true community, great speakers & more! 👉 What made it special & what’s next: javapro.io/2025/05/30/cin… @Sharat_Chander @mstoodle @brjavaman @MarkusKett

@RichardFichtner Congratulations, Richard! We have always appreciated your support and I’m very happy to see you achieve this recognition! Very well done!

Being named an #IBMChampion for 2025 is an honor, but more importantly, it’s an opportunity to continue advocating for technologies that make a real impact in the Java ecosystem. One such technology is the IBM Semeru Runtimes, powered by Eclipse OpenJ9—an open-source JVM designed for performance, efficiency, and cloud-native workloads. Why should Java developers care? ✔ Faster startup times – Ideal for microservices and cloud deployments ✔ Lower memory footprint – Helps reduce infrastructure costs ✔ Optimized for containers – Better performance in modern cloud environments For me, contributing to the Java community—whether through sharing insights, answering questions, or speaking at conferences—has always been about enabling developers to make the best technology choices. That’s why I’m excited to continue this journey with the IBM Champions program and connect with others who share the same passion. A huge thanks to @IBM for this recognition! Looking forward to engaging with fellow champions throughout the year and at #IBMTechXchange. Learn more about the IBM Champions program here: ibm.com/champion

@Sharat_Chander Everyone hail to the pumpkin king!

@lofidewanto @OpenJDK @openj9 @IBM Hi! Please open an issue at GitHub.com/eclipse-openj9…

@mstoodle @OpenJDK @openj9 @IBM I always wanted to reach to you. I tried to build my GWT project with OpenJ9 but it didn't work. It seems, it misses some classes "ClassNotFoundException". github.com/lofidewanto/vi… Where could I create a support ticket?

Look at that! Semeru Runtimes Open Edition for Java 23 release binaries are now available! See: github.com/ibmruntimes/se… . Open source with amazing work by @OpenJDK and @OpenJ9 communities, built and tested by @IBM!

@t_mammarella @openj9 you’re very kind :)

@mstoodle @openj9 We don't mind a long talk for awesome content :D

Thanks @mstoodle for your talk on @openj9 at the Toronto JUG this evening!

FIPS 140-3 certified cryptography underneath our open source OpenJCEPlusFIPS JCE provider is now bundled with IBM SDK for Java 8 and IBM Semeru Runtimes for Java 11+ and ready for production use! More details here foojay.io/today/ibm-seme…

@Sharat_Chander Can’t remember the last time I got zero on something :) , but I’m not sad! Seems like pretty respectable company to me!!

@Sharat_Chander No such list is complete without the entirely essential "buffoonery"

IBM has released FIPS 140-3 support bundled into IBM SDK for Java 8 and IBM Semeru Runtimes (both open and certified) for Java 11, 17, 21+ driven by our open source native crypto module based originally on OpenSSL. More details in this short blog: community.ibm.com/community/user…

After 12 years at Red Hat, it’s time to move on. Tomorrow, July 4 is JRuby’s Independence Day! I’m going to need your help to keep the JRuby project going. Sign up for a sponsorship or contact me about commercial support today. JRuby needs you and so do I! ❤️

@Sharat_Chander @openj9 @jcon_conference Thanks, Shar! It was great chatting and reconnecting with you too! Hope we can do it again soon!

My Eclipse @OpenJ9 and IBM Semeru Runtimes talk at JCON 2024, looking at adoption and things we're doing to improve! Thanks again to @jcon_conference for the opportunity to present in a movie theatre!!
