Dear #Java developer, you really shouldn't miss this talk tomorrow.

It will be streamed here: https://www.youtube.com/watch?v=BK1vZQYZofs

#OpenJDK #Leyden #optimization #performance #talk #conference

In his mail "Data-Oriented Programming, Beyond Records", Project Amber lead Brian Goetz described a new #Java concept:

Carrier Classes

A generalization of records that allow us to succinctly define classes with a data-centric API that can participate in pattern matching and reconstruction.

Join me for the premiere on Thursday (22nd) 8am CET:

With the release of version 0.13.0, NullAway’s support for JSpecify continues to improve. A huge thank you to Manu Sridharan and all the contributors involved! https://github.com/uber/NullAway/releases/tag/v0.13.0 #java #spring

Your project has 2,000 tests—and nobody knows which are #JUnit4. Jean Donato explains how @OpenRewrite and Dependency Analyzer help you migrate safely, step by step.

I’ve been spending time with Java’s Foreign Function & Memory API lately.
It finally makes calling native libraries feel explicit and honest.

In this article, I build a local speech-to-text service with Quarkus and whisper.cpp.
No Python. No JNI wrappers. Just Java talking directly to native code.

If you care about local AI and clear boundaries, this one’s for you.

That said, we are in dire need of a good, simple, robust cross-platform application binary format. Something like #Java .

I mean, we have WASM, but that's hella cursed. :P

@dmoonfire @rl_dane

That said, we are in dire need of a good, simple, robust cross-platform application binary format. Something like #Java .

But definitely something more implementable than the Web browser... HTML5, JS, CSS et al have gotten way out of hand.

I really think #Gemini #GeminiProtocol is on to something with deliberately limiting #extensibility .

❓ What happens when your batch job goes from “it works on my laptop” to out-of-memory errors and accidentally DDoS-ing your own dependencies?

Hugo Marques (Netflix) breaks down the evolution of a high-scale #SpringBoot + #gRPC workload: from single-threaded prototypes to #VirtualThreads & semaphores.

Through practical examples and code walk-throughs, he explores the trade-offs of concurrency tools - and why “just making it async” isn’t enough.

Introduction In this post, we dive into a more advanced topic: pointer arithmetic in Java. With the introduction of the Foreign Function & Memory API (Panama), we can interact with native memory. Usually, when we work with off-heap memory, we use MemorySegment instances to ensure safety. However, creating these objects can sometimes add overhead. In…...

Fluent functional #assertj tests are super annoying. I like how they look and feel, but once something breaks they just don’t give any info back. “Expected to satisfy all of … but didn’t”, cool, thanks a lot.

2025 was a great year for #Spring and #Java

https://spring.io/blog/2025/12/30/this-year-in-spring-december-30th-2025

Yesterday, on my live coding #Java stream, I spent some time (more than I expected) creating some very rough benchmarks for my #EventSourcing example app, JitterTicket.

I had #Junie write a data generator to create 100 concerts, 1,000 customers, each buying 2-4 tix per concert.

Java as a scripting language?
Yes. And it’s actually good now.

I just published a hands-on guide to JBang: single-file Java, instant execution, inline deps, real CLI tools, even Quarkus APIs.

I broke down Event Sourcing in Quarkus using Java records, sealed types, pure functions, and a clean CQRS split.

Fully hands-on. No magic. Just data, folds, and clear architecture.

JEP 500 prepares the Java ecosystem for final field integrity in JDK 26 by restricting deep reflection mutations - closing a long-standing loophole in the platform.

What's new:
• Enhances safety & performance
• Stricter encapsulation
• Introduces developer warnings when mutations are attempted
