I'm happy that my talk "Code not required! The many ways to support open source projects" has been accepted for @jcon.one 2026. 🥳 See you in Cologne next year (April 20-23 2026) :) #JCON2026

Nice. I got accepted at @jcon.one 2026 in #Cologne in April. Hear my explaining everything you need to know about #Java and #Jspecify. Looking forward to it and thanks to @richard.fichtner.dev not minding my small rant in one of the submission text fields :D

As there is a shortage of decent 🖼️ image processing filters in (native) #Java, I am surprised that Jerry Huxtable's Java Image Processing Classes are not in #Maven Central, yet. Well, hopefully next week they are 😎. #opensource #MIT github.com/ghillert/ima...

Mit guten Vorsätzen, wie z.B. die JUG besuchen, könnt Ihr bei uns sogar schon vor dem Jahreswechsel beginnen. Wir haben soeben die Anmeldungen für den 22. Januar 2026 freigeschaltet und freuen uns auf @nipafx.dev mit seinem Vortrag über Java 25. www.jug-ostfalen.de/event/2026/0...

What's new on Learn.java this week? - array practice - array tutorial images to illustrate what it looks like - String split method practice - 2D array tutorial - December newsletter - Recording of J Card Visuals with Text Blocks

#ITTage in Frankfurt is always a great way to end the conference year. ✨ Had a lot of fun presenting on #Java 25 features, exception handling, and OpenJDK projects, but the AMA I got to do was my highlight. Looking forward to doing that more frequently in 2026. 😃

Lots to talk about! If you want to follow up or check out what we had to skip, here are the slides: slides.nipafx.dev/java-x/2025-... Btw, I'll spontaneously fill in the 1pm session - let's talk about exceptions: www.ittage.informatik-aktuell.de/programm/202... #ittage

#Java 26 enters rampdown phase 1 today, which sets its feature set in stone. The latest inside Java Newscast goes over the full list (don't click, it's boring): www.youtube.com/watch?v=RPX5...

JUnit is undoubtedly one of the most important projects in the #Java ecosystem. And it's 100% free and open! Let me be frank: If we can't get THIS project to the point where a single maintainer can focus on it, then what does that say about our commitment to Free & Open Source Software? 1/3 ⏩

If you use reflection in #Java, be aware that, starting with JDK 26, you may have to add a command-line option or two to keep it working. Alternatively (and recommended), move away from reflective final field mutation. Details in the latest Inside Java Newscast: www.youtube.com/watch?v=bdHk...

This is your chance to share a stage with Java's greatest. (Or with me if you're unlucky.)

Not all answers to your questions about the Inside #Java Newscast made it into the jubilee episode and so I posted the remaining ones to my channel - about how the team works together, how much I still code, how AI may impact my work, and more: www.youtube.com/watch?v=TypH...

#jfmt v0.1.0-rc1 - the very first release - is out! It's a CLI based #java code formatter, made with GraalVM, #Eclipse JDT and PicoCLI github.com/bmarwell/jfm... Let me know what you think of the general approach!

Project Valhalla updated JEP 401 ("Value Classes and Objects") and released a new EA build. That's a good opportunity to: 🤔 reset understanding/expectations 🎫 go into object identity ⚡️ discuss optimizations ⏰ answer "Valhalla, when?" Latest Inside #Java Newscast: www.youtube.com/watch?v=Eua3...

As always, #JFall was a blast - thanks for having me and letting me tell people about the latest #Java features. 🙏 Slides: slides.nipafx.dev/java-x/2025-...

The next Inside Java Newscast will be episode #100. 🤩🥂 It'll be about the recent Valhalla news, but after that, to celebrate the jubilee, I'll answer your questions about the show and the team behind it. Put your questions below. 👇🏾

📢 Announcement 📢 #Java peers, the 2026 #JavaOne call for papers is now LIVE. Please make your submissions by November 11, 2025 5:00 p.m. PT by visiting the conference website: ➡️ social.ora.cl/6013A7UXF

The best #Devoxx session (in my book) is about to start: Ask the Architects. Bring your questions about Java and the OpenJDK architects will answer them. See you in five!

Project Panama is a key component for transitioning #Java into the #AI era! @tornadovm.org has been among the early adopters of Panama. Thanks @nipafx.dev for the excellent talk @devoxx.com and the shoutout!

Brian won't be there, so don't even bother with "Valhalla, when?". 😉

What to do on a fine Sunday? Why not listen to Brian Goetz (and me - sorry, couldn't be helped) about how #Java features are delivered incrementally and how Projects Amber and Valhalla come in feature arcs. 🌠 (Links to some platforms in the next message.)

Setup for tomorrow... 🤓 www.youtube.com/live/duIceCX...

Java 25 lands tomorrow! 🚀 But you don’t need to wait to try its features – IntelliJ IDEA 2025.2 already comes with early support for Java 25. 🔗 jb.gg/java25-support P.S. Don’t miss the Java 25 Launch Event tomorrow: jb.gg/java-25-launch

As a JUG leader, I sure hope in-person events aren't dying off, but it sure seems like it's getting harder and harder to keep this all going. www.brentozar.com/archive/2025...

I'll be there to chat with you because Lazybones Billy (our nickname for him when he's in earshot) will be tucked into bed. Just because it's 4am for him - unbelievable. Anyway... See you there?

This is pure gold, I laughed from the beginning till the end! Everything you need to know when upgrading to the next Java LTS version (actually...), presented as a short, office comedy-drama. Good job upgrading to JDK 25, Peter! 👀

Updating from #Java 21 to 25 is a smooth experience. Mostly - a few details changed: annotation processing, inner class constructors, file operations, the removal of old technologies... Watch our first #RoadTo25 video to learn everything you need to know: www.youtube.com/watch?v=9azN...

You asked about: * training runs * identity-based records * if expressions * web assembly * and more The #Java Architects answered: www.youtube.com/watch?v=OMqw...

📺 Join our Developer Advocates for a special IntelliJ IDEA Talk episode focusing on the 2025.2 release highlights! Enjoy hands-on demos, feature deep dives, and real discussions about what matters for your workflows! 📅 Check out the agenda and set a reminder: www.youtube.com/live/_nt-z0F...

#Java peers, During this year's #JVMLS, the Java Team from #Oracle is holding an "Ask The Architects" session. Reply HERE with questions until Aug 3. Pls make sure to read suggested questions first and upvote what you like to prevent double-posting. Watch answers on Aug 14th at youtube.com/java

HTTP/3 has lower latency, loads more quickly, and leads to less network congestion - all good reasons for #Java to adopt it, which is what JEP 517 proposes. More in the latest Inside Java Newscast: www.youtube.com/watch?v=WphR...

#JUnit 5.13.3 is released! 🐞 Bug fixes and minor improvements junit.org/junit5/docs/...

The latest Inside Java Newscast explains why #Java 25 is ALSO no "LTS version" (just like 11, 17, 21 weren't) as well as why that matters, why it's important to talk about this the right way: www.youtube.com/watch?v=x6-k...

Ey, ey, ey, so much going on, I forgot to tell you about my vacation Newscast. 🤦‍♂️ Check it out to learn how to transform cryptographic objects to PEM texts and vice versa with #Java 25 (or to speedrun my Ibiza vacation): www.youtube.com/watch?v=hqvM...

#Java 25 is frozen! 🧊 It finalizes 11 features in the language (e.g. simplified main), APIs (e.g. scoped values), and runtime (particularly AOT and JFR) and has 7 more in preview. Walk through the complete list in the latest Inside Java Newscast: www.youtube.com/watch?v=T5q7...

OTD…May 23, 1995 Happy Birthday, #Java! Here’s to 30+ more years with a beautiful combination of technology innovation and community participation!

Brian Goetz just joined the #Java 30th birthday live stream to tell us about how he (and his team) added lambdas to the language: www.youtube.com/live/LHHPbI7... You don't want to miss this! (Nor let the slight audio issues stop you.)

#Java 25 is shaping up to be another BIG release! 🚀 Currently targeted final features: * simplified main * flexible constructors * module imports * scoped values API * key derivation function API * compact object headers

"Towards a JSON API for the JDK" New proposal on the core-libs-dev list for adding a basic JSON API to #Java. That would be a more than welcome addition, in particular considering the envisioned usage once member patterns will be available. Make it So 🤩! mail.openjdk.org/pipermail/co...

Another excellent video of Inside Java Newscast from @nipafx.dev explaining the newly proposed changes (mainly Joiner API) to Structured Concurrency in Java. 🎥 ☕️🧵

😹

Just got caught up in the latest round of terminations from Microsoft. If anyone needs a "batteries included" advocate who really knows code, AI, and real production concerns + solutions, ping me! Ready to make great things happen for you. Onward and upward!

After virtual threads, structured concurrency is the next big step for concurrency in #Java. All the more important to get it right! JEP 505 overhauls the proposed API in Java 25. Learn all about that in the latest Inside Java Newscast: www.youtube.com/watch?v=vLJD...

Java stream's terminal operations `findFirst` and `findAny` are neat but one use cases isn't covered: "find the only one" - a terminal operation you'd use after a filter that's supposed to let exaxctly one element pass through. There's now a JDK preview with that operation, named `highlander`. ⚔️

Java Time Capsule was such a cool idea! Last time seen in the hands of @smarks.bsky.social, asking if anyone has a shovel #javaturns30
