@sdkman.io are there a specific reasons why the OpenJDK 28 EA releases are not yet available?

@bellsoft.bsky.social I just stumbled accross the nonroot and distroless image tag parts for the bellsoft/hardened-liberica-runtime-container. Is there a specific reason these are not documented at bell-sw.com/bellsoft-har... and I can't find any meaningful documentation/information at all?

According to jdk.java.net/27/ the latest @openjdk.org EA release for #java 27 is build 30. But my @sdkman.io (MacOS, ARM) lists 27.ea.25-open as the latest one. Does anyone get a newer build offered? And does anyone know how to debug or where to report this? Thanks.

Anybody here using #docker sandboxes with #claude code in Java projects? Wonder how you install specific JDK/Maven and make sure it's correctly picked up by the agent.

@intellijidea.com I'm using 2026.2 EAP and last week I noticed that there is no auto completion popup while typing extends after a class declaration. 2026.1.2 and .3 Preview shows the popup for the keyword. Is there an option that I might have disabled by accident or is this a bug?

Does anyone know why the #spring security reference documentation (docs.spring.io/spring-secur...) is not longer reachable? /cc @garnier.wf @odrotbohm.de

@bellsoft.bsky.social is there a specific reason why @sdkman.io offers me 8.0.492.fx-librca but only 8.0.482-librca and not 8.0.492.-librca?

If your IntelliJ burns through tokens too fast, just enable the new optimized AI by putting an empty file named .noai into the root folder of the project. Problem solved. Thank me later. ;-)

Does using AI assistance during a pair programming session already count as ensemble programming?

When I told that my journey of learning CSS to improve my website's style ended in changing my shell from bash to zsh I was laughed at. Since yesterday, I can add that after bubbling up the stack again, I found out that I need to switch my static site generator. I fear people will stamp me as mad.

@seb.deleuze.fr and @snicoll.be do you know if jspecify/or nullaway allows a way to declare that a variable that is annotated with @PathVariable(required = false) and is not an Optional is automatically marked as Nullable?

If you visited my talk, “What? That's possible in #Java?” at @devoxx.com last week or already watched the recording on YouTube (www.youtube.com/watch?v=DfeC...), you can now also check out the examples on GitHub (github.com/mvitz/wat-ja...).

Recently, someone asked if I know companies that work within the core #java universe (like JDK vendors, tooling, no pure consulting) and are willing to hire people from Germany who can work from home. As I have no clue, please ping me if that matches your company. Please don't hesitate to repost.

My friend @meistermeier.com wrote a nice post about #SpringBoot #Actuator meistermeier.com/2024/12/28/S... and why it is *not* insecure by default, in contrast what the folks at CCC implied. TL;DR: #VW apparently enabled it on purpose, opted out of security and went straight to production.

My latest magazine article 🇩🇪 about integrating #LLM into #Java based #Spring applications via #SpringAI can now be read online at www.innoq.com/de/articles/... It’s mostly about the basics but shows some RAG, Function Calling and Observability, too. Hope you enjoy it.

If you're curious about #java and the #jdk ecosystem, you should attend jchampionsconf.com. This is a @javachampions.bsky.social run online conference split over four days. Of course, everyone can attend for free, although you have to register in advance. Hope to “see” you there.

After upgrading to #SpringBoot 3.4 and using the new webjars-locator-lite our internal WebJar package wasn't working any more. Because others may stumble over that problem too, I wrote a short post about why that happened and what you have to do to fix that: www.innoq.com/en/blog/2024...

Switching to the new webjars-locator-lite, e.g. by following the Spring Boot 3.4 Release Notes, may result in errors when loading your internal WebJars. This post explains why that is the case and wha...

It’s hard to believe that there was a time in #java without annotations. In my latest article, you can see how we solved problems back then and how things could work without them today: www.innoq.com/en/articles/...

Der #LLM Hype zieht auch an mir nicht vorbei. Deswegen habe ich mir angesehen, wie diese lokal betrieben werden können und wie mit #SpringAI eine Integration in #Java funktionieren kann. Meine Eindrücke und Gedanken habe ich dabei schriftlich festgehalten: www.innoq.com/de/blog/2024...
