@jcon_conference @IBMDeveloper @OpenLibertyIO @openj9 JCON2024 workshop "Java with Ultra Fast Startup and Remote JIT Compilation", see README.md to run in a container on your laptop. Includes pdf of my slides so it's a bit beefy: git clone github.com/mstoodle/jcon2…

I so wish I could have joined the group…One of my favourite conferences but, alas, was not in the cards for me this year. Happy to see such strong group representing and supporting @IBM there!

We’re excited to announce the release of Eclipse OpenJ9 v0.59.0 🎉 Get it now at ibm.biz/GetSemeru and explore the latest improvements. Curious about OpenJ9 GC policies♻️? We’ve included a quick overview below with a deep-dive article coming soon. Stay tuned!

Sadly, I cannot be there this year, but JCON is definitely a premier event everyone should be trying to get to and make sure you chat with the IBM team that will be there! Also, Cologne is an amazing city to visit!

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!

I have the THE BEST neighbors! Happy holidays!

@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!!

If your total score is ZERO like mine, we can be friends.

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

How many of these words have you ever used in a work email?

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…
