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?

#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.

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 ☕.

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

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.

BellSoft @bellsoft.bsky.social · 8d

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.

BellSoft @bellsoft.bsky.social · 8d

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 🧵

📖 Docs and JEPs
Updating JavaDocs, writing guides, or explaining APIs is a contribution too.
And if you have a bigger idea? That’s where JEPs come in – the formal process behind features like Records, Virtual Threads, and Pattern Matching.

👀 Reviewing code
You don’t need committer rights to review changes. Feedback on clarity, performance, or test coverage is always welcome. Reviewing is also the best way to learn OpenJDK internals before proposing your own patch.
