JavaOne

Join the world’s premier developer conference in Redwood Shores, CA
March 17–19, 2026

[Java @java]

In 1995, a small team of engineers unveiled a new programming language designed for flexibility, portability, and robustness. That language was Java. And three decades later, it remains one of the most influential technologies in the software world.

Thank you for helping us celebrate #30YearsOfJava this past year. We look forward to many, many more years of pushing the boundaries of innovation and the pursuit of developer excellence. ❤️

[JavaOne @JavaOne]

JDK 25 is the first release that includes the FFM API and has broad long-term support. Learn how this allows us to avoid the previously slow, brittle, and complex process of using JNI and ByteBuffers in this #JavaOne talk. https://t.co/k6seYxv8No

[JavaOne @JavaOne]

This #JavaOne session highlights the progress of JEP 528, which brings core dump and minidump support to jcmd.

Watch now for a deep dive into the future of JVM crash analysis and post-mortem diagnostics. https://t.co/b6ehKBOHBt

[JavaOne @JavaOne]

What's the state of structured concurrency and Project Babylon? How is Java being developed and what role does AI play in that process?

You brought the questions. The architects had the answers.

Check out our "Ask the Architects" session from #JavaOne. https://t.co/9xtN8WEjEE

Attended my first JCP Executive Committee meeting! ☕️

Honored to guide Java's evolution alongside industry leaders.

Presented updates on Brazilian JUGs with @brjavaman, highlighting university outreach for the #JavaInEducation group.

Shaping the future. 🚀

JavaOne is over. And it was a really good one.

Huge thanks to the Java DevRel team at Oracle.

You notice when people care about what they’re building here.

For me, the best part was the conversations.
Not the talks. The hallway track.
Talking directly to the people working on Java. Getting their unfiltered view. Hearing how things actually work and where things are going.
That’s the stuff you don’t get online.
Also - very well organized. And yes, the food was great (not comparable to JavaOne from 10 years)

I gave two talks around the Java ecosystem: The core idea was simple: Java can do a lot more than many people think. I showed how tools like OpenRewrite, Vaadin and EclipseStore help you move faster and get more out of your applications without throwing everything away.

And then there was the ribbon game.
Luiz Real and Ivar Grimstad took it seriously. Really seriously.
Just look at their badges.

Next stop is JCON Europe in April: https://t.co/q8dWCxGkE1
The Oracle team will be there. If you want to have these kinds of conversations, that’s the place.

It was an honor to be among my fellow Brazilians over the past few days at #JavaOne

It was a busy week, and no one felt that more than Duke. Go through a day in his life as he made his way around #JavaOne.
