Released Jenesis 0.10.0, after building a first larger modular Java app without a single POM. Works without glitches now and is rather fast. Try it! github.com/raphw/jenesi...

A modern Java build tool: Java-native config, plugin-free, with module-info.java treated as a feature, not an afterthought. - raphw/jenesis

Jenesis 0.9.0 fully supports SBOMs and automatically creates them now and improves on automated licensing and vulnerability constraints. With all it knows how to do (github.com/raphw/jenesi...) what would still be missing?

Jenesis now offers all features build tools out there offer through configuration, but by detecting configuration files in the main folder. I would expect that most developers will meet a feature complete tool. Try it out: github.com/raphw/jenesi...

Added implicit support for jmod, jlink and jpackage to Jenesis,for those that want to use it. Samples are in the demos. Should now also build most POM projects without needing Maven. github.com/raphw/jenesis

I added support for most JVM languages to Jenesis and polished the framework altogether. I also added a range of demos: github.com/raphw/jenesi... If you are interested in build tools and always thought that building on the JVM should be easier, maybe this approach is for you. Let me know!

Out of the 1000 most downloaded artifacts from Maven Central, more than a third are not actively maintained. commons-io is the second most downloaded artifact. That is a little bit sad. github.com/raphw/jenesi...

I think I came up with a reasonable alternative for a build tool for the JVM. To give you a teaser, I want to get rid of the POM, but offer compatibility to it, given they are anywhere, but want to embrace Java Modules which work really well for this. State of modules: github.com/raphw/jenesi...

As amazingly well Claude and Codex are working as tools; they are not useful as pair programmers in my eyes, as they are never pushing back. Makes me wonder how broad the need for maintenance of technical debt will affect worker productivity. The best code is the one you don't write, still.

As an old and somewhat inactive Mockito maintainer I'd like to congratulate Tim for these past years keeping the light on the Mockito project. He his now stepping down. Thank you Tim. github.com/mockito/mock...

Stepping down as maintainer after 10 years · Issue #3777 · mockito/mockito

In March 2026, I will be Mockito maintainer for 10 years (nearly a third of my whole life). Looking ahead, I decided that a decade milestone is a good moment to pass on maintainership to other folk...

I had the pleasure of traveling home to Munich to talk to Marco about software, and I quite enjoyed it! And I will hope you will, too. Thanks for having me.

New deep-dive on The Marco Show! 🎥 Watch now: youtu.be/AzfhxgkBL9s Marco sits down with @rafaelcodes.bsky.social (creator of ByteBuddy) to unravel JVM internals, bytecode instrumentation, Mockito and Hibernate internals, legacy Java realities, and the challenges of maintaining open source at scale.

Help--my LocalDate isn’t flattened! Just before my Valhalla talk at JFall, I found out that the early access build can flatten LocalDate arrays, but the latest version from Github cannot. Why? Serialization, of course. Read the gory details at https://horstmann.com/un...

Wow, TIL that LISTEN/NOTIFY in Postgres requires a global lock when committing transactions issuing a NOTIFY. Consider listening to the WAL via logical replication as an alternative with no impact on the write path. www.recall.ai/blog/postgre...

"Towards a JSON API for the JDK" New proposal on the core-libs-dev list for adding a basic JSON API to #Java. That would be a more than welcome addition, in particular considering the envisioned usage once member patterns will be available. Make it So 🤩! mail.openjdk.org/pipermail/co...

Und das, liebe Kinder, ist der Grund, warum man sich bei existenziell wichtigen Werkzeugen am besten mindestens parallel auf lokal gehostete Open Source Lösungen stützt. Wenn #Trump anfängt, die US-Tech-Konzerne in Waffen zu verwandeln, wird es finster. #KritIs

Here's something I want but am too lazy to build: Take a picture of a huge pile of Lego, and get me a classification of what brick belongs to which set. The manual equivalent is quite something.

We just integrated a performance improvement to Java String that will provide a ~10x performance boost in some applications where Strings are used as keys and where the associated values are constant foldable. This will make JDK 25 faster. github.com/openjdk/jdk/...

Do I understand it correctly that the central-publishing-maven-plugin intends to replace the nexus-staging-maven-plugin? But not necessarily the maven-release-plugin? How would one otherwise handle tagging in Git? I'm confused.

We’d love to see more talk proposals rolling in for #JavaZone2025! Got something interesting to share? Big or small, wild or practical — we want to hear it! 🙌 2025.javazone.no/en/...

My first question on Stack Overflow in four years. Any ideas why Kotlin reflect cannot observe an annotation if a class's "flag" is 6 and not 7? stackoverflow.com/questions/79...

Dynamically added annotation is not visible to Kotlin reflection

I am working with a Java agent that is adding an annotation dynamically to a class file. When this class file is a Kotlin class, and if it is investigated by Kotlin reflection, the annotation does ...

stackoverflow.com

What frustrates me most about Kotlin and Scala is their closed world perspective on their own tooling. Java byte code is well-defined and easy to interop. It should not be hard to add an annotation to a class, but with Kotlin it somehow is: discuss.kotlinlang.org/t/dynamicly-...

Dynamicly added annotations are not visible

I am trying to add support for kotest for a test intelligence tool. To do so, I need to be able to add the Ignored annotation to classes dynamically using a Java agent, but the annotation seems to not...

All folks who speak at conferences should read this and think long and hard about whether they want to risk speak in the US in the future. Also anyone who works while traveling. comicon.com/2025/03/18/f...

Catch of the day: The Kafka client for Java logs a bunch of things on info level that likely should be debug, which resulted in Splunk logging for millions of crowns of repetitive things nobody needs. I argue that libraries should never log anything on the info level.

@vonderleyen.ec.europa.eu Here’s a potent idea for Europe: allow member states to charge VAT on online ads served within their borders. Why should platforms like Meta earn ad revenue from EU audiences without paying VAT locally?

One of my most radical political positions is that online ads should be treated like addictive substances (alcohol) and have something like 100% VAT. This doesn’t exist because governments can’t technically charge VAT for online ads served in the country.

Finally found the time to make Mockito a proper named module: github.com/mockito/mock... jdk.unsupported can still be used, but if Mockito is added as an agent and the package is not imported elsewhere, it still works fully without it on official API in the instrumentation API.

Add support for including module-info in Mockito. by raphw · Pull Request #3597 · mockito/mockito

Adds module-info.java to describe module descriptor.
