Is Java Cloud Native? How Java Became Perfect for Cloud Native Applications - JAVAPRO International Explore how Java transformed into a cloud-native language with Docker, Kubernetes, and CI/CD, providing fast, efficient container deployments.

Is Java really cloud native? ☁️ After 30 years, the platform looks nothing like it did – from container awareness and minimal images to native builds and virtual threads. Dmitry Chuyko breaks down how #Java became a first-class citizen in the cloud world: javapro.io/2025/07/29/i...

Is your #Java app slower than it should be? @cat-edelveis.bsky.social breaks down how to profile it properly – from JFR and VisualVM to Async Profiler, YourKit, and more. Learn how to find what’s eating your CPU or memory: youtu.be/APvwi1SiFTw

Devoxx Belgium is over. Lots of good talks, plenty of hallway chats, and many great people at our stand.
Congrats to Kevin Schuddinck, the winner of our Steam Deck raffle! 🎉
Thanks to everyone who came by – see you at the next Devoxx! 🩵

Our lightweight OS is officially a toddler 🦙
This fall, Alpaquita Linux turns three! Born small, secure, and optimized for #Java – still keeping containers lean and zero-CVE three years later.
Here’s to many more builds ahead: bell-sw.com/alpaquita-li...

The Steam Deck raffle is almost over 🎮
Join us at stand 24 today, Thursday Oct 9, at 16:15 for the winner announcement. Still a bit of time left if you haven’t joined yet – don’t miss your chance! #Devoxx

Looking for a legal performance boost for your #Java apps?
Tomorrow at #Devoxx Belgium, Dmitry Chuyko explores JVM “dopes”: Leyden, CRaC, Lilliput, Graal JIT, native images, fused JDKs.
How far can you go without rewriting code?
📅 Thu, Oct 9 • 12:55 • Room 5

We’re at booth 24 at #Devoxx Belgium. Lots of good conversations already – stop by if you want to talk #Java, performance, or containers.

Still on Java 8 or 11? You’re not alone.
Tomorrow at #Devoxx Belgium, @asm0dey.site (#BellSoft) and @jbaru.ch (@TuxCare) show how to make legacy #Java feel better – cleaner code, safer apps, faster runtime, without forced rewrites.
📅 Thu, Oct 9 • 13:50 • Room 7

#Java25 adds compact source files with instance main methods. No more complicated public static void main, just a clean entry point.
Perfect for PoCs and teaching.

Our team is at #Devoxx Belgium this week. You’ll find us at stand 24, where we’re discussing JVM performance, container efficiency, and #Java security with the community. We also have a Steam Deck raffle at the booth – stop by and take part!

One important improvement in #Kamal 2.x is that #curl is no longer required for your #Docker images in order to perform health checks. That way way you can use slim base images, e.g. @bellsoft.bsky.social 's Alpaquita based image for Liberica #Java, e.g. jdk-25-cds-slim-musl ☕.

In Berlin this week? Don’t miss tomorrow’s talk at Berlin Expert Days 🎤
@asm0dey.site will show how #Java apps can start in just 5 ms – without native images – using #CRaC (Coordinated Restore at Checkpoint).
🗓️ Tue, 10:20–11:20

Top 7 Mistakes When Testing JavaFX Applications Testing JavaFX programs may seem non-trivial at first. This article describes the most common mistakes when testing desktop apps, their causes, and solutions.

Testing #JavaFX often fails for common reasons: touching UI off the FX thread, racing the event queue, flaky pixel checks, Monocle misconfig in CI, FXML classloader traps.

Many teams still rely on Lombok, but few realize what it actually does under the hood. In this video, @cat-edelveis.bsky.social explains how Lombok rewrites your code and when it might be safer to move on: youtu.be/D-4mWspCz58

Alternatives to Oracle Java — Overview of OpenJDK distributions Discover the key characteristics of the most popular Java distributions

📚 If you’re planning a migration, here are three resources. Oracle Java alternatives: bell-sw.com/blog/oracle-...
📚 Migration guide: bell-sw.com/blog/how-to-...
📚Java 8/11 EOL risks: bell-sw.com/blog/oracle-...

OpenJDK distributions offer a way out. They are TCK-verified and compatible with Oracle JDK, provide longer free update timelines, and offer support prices based on infrastructure size rather than employee count.

The outcome for enterprises: higher costs that grow with employee count, upgrade pressure, and sudden changes to Java SE products roadmap.

September 2025 brought another shift. Just a few days before JDK 25 release, Oracle announced that GraalVM for JDK 24 was the final GraalVM release licensed and supported as part of Oracle Java SE products.

For older versions, the deadlines are known. Free updates for Java 8 and 11 ended in 2019. Paid support for Oracle Java 11 ends in September 2026, and for Java 8 in December 2030.

In 2023, the pricing model shifted to the Java SE Universal Subscription. Instead of licensing per server, costs are now calculated by total employee count. This meant dramatic budget increases for many enterprises.

The NFTC license introduced with JDK 17 offers only three years of free updates per LTS release. That window closed for JDK 17 in September 2024. It will close for JDK 21 in September 2026. After that, you upgrade or pay.

In 2019, Oracle ended free updates for Java 8 used in production. Running a secure JDK now meant buying a subscription or switching vendors.

Oracle frequently changes the rules of Java licensing. Costs tied to the total number of employees, new schedule for free updates, GraalVM pulled out of Java SE. Here’s what’s changed in recent years and why many companies are moving to OpenJDK 🧵

#Java25 adds scoped values, a safer alternative to thread-local variables. Cleaner state sharing, less hidden leaks, perfect for virtual threads:
