Spring Boot 4.1.0-RC1 available now Notable new features include: - Support for OpenTelemetry SDK environment variables - HTTP Client SSRF Mitigation with InetAddressFilter - Support for LazyConnectionDataSourceProxy spring.io/blog/2026/04... #spring #springboot #java

GitHub appears to have opted anyone using the CLI into sending telemetry they will use to inform product decisions. This is sneaky and should have been an opt-in decision, not opt-out. Disable it with `gh config set telemetry disabled`. cli.github.com/telemetry

Made very few changes to the latest build and was thinking maybe I'll be able to ship this one without incrementing the shame version (last number in a version number) and 2 minutes into testing, it's already getting bumped.

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 pretending to be customer support is a pretty miserable experience. I don't need something pretending to be human regurgitating the FAQ page. It must also put a strain on the real support staff who now only get customers who are already angry from fighting a robot!

🐞 Debugging done right saves hours of pain. In his #Devnexus talk, @philwebb.dev shared the “Three R’s” of debugging—Reproduce, Report, Repair—backed by a decade of Spring Boot experience. Recap it here ⤵️ devnexus.org/posts/how-to... 🌍 Join the conversation in person at #Devnexus 2026!

This is your last chance to get cheaper early bird tickets for DPE Summit in September. This is THE conference to go to if you want to hear how different companies of different sizes and domains are improving their developers' productivity dpe.org/dpe-summit/

Imagine you're into cooking, then one day microwave meals are invented. Suddenly, all the cooking shows talk about are microwave meals. Magazines, books, ads and chefs pivot to microwave meals. Everyone will eat them and they'll be worth zillions! Anyway, let's talk about AI

Someone asked for an investigation as to what went wrong with the Spring Boot 3.5 release this month. Here's more background for those interested: github.com/spring-proje...

Fantastic work by me throwing coffee absolutely everywhere this morning! The problem with a nice espresso machine is you need at least two coffees inside you before attempting to operate it 🤣

Hire Mark! He is not only a great advocate and speaker, but a wonderful person.

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!

It seems to be "hate on Lombok time of the year" and "what has Lombok ever done for us"… I am tired. - Just don't use it if u think it stinks - Don't use it as library author so that you don't force it onto others - Use it the hell you want in your enterprise application, nobody cares about anyway

Hello #java bubble! Does it make sense to have a jakarta.servlet.Filter which are configured with none of the available jakarta.servlet.DispatcherType ? E.g.

Nice. Looking forward to meet you all in Barcelona!

If you were at my recent Java one or DevNexus talk this will help a lot to translate what I did in Eclipse to IntelliJ. Actually, it's even clearer than what I showed, and it's under 10 mins!

Feels weird to post about the little stuff at the moment, but I'm talking at both Devnexus and JavaOne this year about debugging issues. I'm very happy with the way the presentation is coming together. Distilling 10 years of tracker content into 60 mins is pretty challenging!

Testing milestones and release candidates will be much easier: the spring portfolio will release milestones and RCs of the next major onwards to Maven Central spring.io/blog/2025/01...

If you're in the San Francisco area and need a little escape, come to the SF Java User Group tonight. @starbuxman.joshlong.com and myself will take you back in time and talk about 10+ years of Spring Boot. It should be a really fun talk! www.meetup.com/sfjava/event...

Me, wisely: All code styles are basically equivalent; each team should simply pick one and stick with it. Style wars are the sign of a lesser mind You: OK, given that, can we use my preferred style instead of yours? Me: Fuck off directly into the sun with your unreadable indentation rules, no

One of those days!

I'd like to thank my 1080p and 720p friends, but not my low res 480p friends!

This week at the JUG SF meetup we explored the journey from #code to #cloud w/ @localstack.cloud. 🎥 coming soon. Slides include: 🚀 Developing & testing cloud apps ✅ CI/CD integration made easy 🌐 Ephemeral instances for open PRs ☁️ Seamless deployment to AWS 🔗 speakerdeck.com/ancaghenade/...

I'm adopting a new harder line open source maintenance policy

TIL about regex101.com. So good! Especially for someone regex challenged like me.

Hi, I'm using your software for free and have encountered a problem that I will now not even attempt to describe. FIX THIS NOW or I will stop using your software for free. Here is a screenshot of my terminal window.

Personally, I like the json logging support.

I like this analogy, but I've see a few places where management don't like you touching the trays because it's not your job!

Big thanks to @dashaun.com for making this go so well. A great host makes things look so effortless! m.youtube.com/watch?v=ivKv...

The amount of energy I am having to spend these days thinking about k8s and other general infrastructure-level issues just to build my team’s small set of services is pretty insane.

I feel a little sad realizing that there are friends who are no longer with us so they can never migrate from Twitter.

I feel honored, humbled, and happy. Thank you very much for this recognition, it feels great to be part of this community with all these awesome people! ❤️

Are we posting food pics here yet? Anyway.... a big ass pot of butter chicken 😋
