Every year, someone says Java is dead. This year, I talked to a CTO at IBM about it.

Had the chance to talk to Soufiane Azizi, Field CTO for IBM Data & AI, at IBM TechXchange. We did an interview about a project we did at XDEV with IBM technology. More about that soon.

But we also talked about Java. Soufiane was a Java developer himself for many years, and he told me that Java is really important for IBM. A lot of IBM products are based on Java. And a lot of the systems on IBM Z and IBM i, written in Assembler, C or RPG, are moving to Java.

For a Java person like me, this is great to hear. Java has an important role in the future.

Thanks, Soufiane, for the great conversation!

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!

[💻☕ Richard Fichtner @RichardFichtner]

Really nice to see IBM represented by IBMers and IBM Champions alike at JCON EUROPE. The ecosystem becomes stronger when people from different companies, communities, and backgrounds come together around Java.

Also very cool to see IBM Bob showing off Java capabilities and developer-focused innovation. Java keeps evolving, and it’s good to see IBM actively contributing to that journey together with the community.

[Eclipse OpenJ9 @openj9]

We’re excited to announce the release of Eclipse OpenJ9 v0.59.0 🎉

Get it now at https://t.co/a5L4Qq9Gna 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!

[Mark Stoodley @mstoodle]

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!

[💻☕ Richard Fichtner @RichardFichtner]

Time flies when you’re connecting great people. 3 years already.

Being an IBM Champion was never about the badge for me. It’s about the conversations, the shared ideas, and building bridges between the IBM Java community and the wider Java ecosystem.

Looking back, it’s a lot of small moments. Meeting people at events. Spontaneous hallway chats. Turning “we should do something” into actual collaboration.

Next stop: JCON EUROPE ... IBM is joining as a Platinum sponsor and will be on site with some awesome folks. If you’re there, come by and check out the cool Java tech IBM has built.

[Eclipse OpenJ9 @openj9]

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: https://t.co/uWwskTV3cb

[Mark Stoodley @mstoodle]

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

[IntelliJ IDEA, a JetBrains IDE @intellijidea]

The full JDK lineup is here! You can now use every major Java 25 build, including @IBM Semeru powered by OpenJ9. 🙌 Check out our blog post to learn how to install the latest JDK in your IDE.👇
