Spring Boot 4.1.0-M3 has is available now! spring.io/blog/2026/03...

On behalf of the team and everyone who has contributed, I'm happy to announce that Spring Boot 4.0.4 has been released and is now available from Maven Central. spring.io/blog/2026/03... I hope it's not 404ing. #java #spring #springboot

I won't tell you that Marit and yours sincerely are working on refreshed version of our talk. But there will be signs... ;-)

“If No One Pays for Proof, Everyone Will Pay for the Loss” https://freakonometrics.hypotheses.org/89367 > Even when a result looks correct on a small scale, that tells us almost nothing about its effects on the system as a whole This is what I've been saying for years now to thundering silence.

Java 26 is here, but it's boring. Nothing really exciting. But that's a good thing, as the boring stability is what made Java successful (co-written with @lutskedev.bsky.social): mostlynerdless.de/blog/2026/03...

#Java 26 is here, and its main purpose is to provide a solid foundation for future things to come. It comes with new features, performance improvements and multiple enhancements–my blog post has all the info! 🚀

Most developers now use coding assistants. I do too—#Copilot at work, #ClaudeCode at home. As a developer, I prefer not to repeat myself. This post explains why and how to avoid repetition with skills. #DRY

"Should I search the Web, or just ask ChatGPT?" That depends on whether you actually want to know it.

I recorded an episode of the Marco Show with Marco Behler from JetBrains. It was an absolute pleasure, thanks for having me. We talked about a lot: how I ended up on the Spring team, Project Leyden, GraalVM, AI, and so much more. Also available as a podcast. www.youtube.com/watch?v=FUFs...

AI tools for developers are useful. But they are not enough. If AI is getting better and better at programming, why are we focusing almost all innovation on coding tools? Read more here: martinelli.ch/ai-tools-for-developers-are-not-enough/

Your JPA entities don’t crash when equals() is wrong. They lie. They disappear from HashSet. They duplicate in caches. They fail across transactions. I wrote a deep dive on production-safe equals() + hashCode() for #Quarkus & #Panache — with real tests and EqualsVerifier. buff.ly/koCNR4h #Java

I hate the re-soloing of development. We were so close to learning social skills, creating community, encouraging creativity & purpose, & applying empathy. Easier to manage if each of us is so busy with our genieswarms that we don't have time to talk & reflect.

In this blog, you will take a closer look at Spring Security. More specifically Spring Security in combination with Keycloak using OpenID Connect. All supported by means of examples and unit tests. Enjoy! #java #springboot

Just remembered something I had completely forgotten. We don’t need `-Dfile.encoding=UTF-8` in Java startup scripts anymore. This has been the case since JDK 18, where UTF-8 was set to be the default encoding. I'm on JDK 25 now, so time to cleanup a bit. https://openjdk.org/jeps/400 #java #jvm […]
