If you need to get up to speed with null safety in #Java with #JSpecify and @manu.sridharan.net's #NullAway, watch @seb.deleuze.fr's excellent presentation from @springio.net 2025.

Nice. I got accepted at @jcon.one 2026 in #Cologne in April. Hear my explaining everything you need to know about #Java and #Jspecify. Looking forward to it and thanks to @richard.fichtner.dev not minding my small rant in one of the submission text fields :D

Enjoy my new, artisanal blog post about #JSpecify and #NullAway, a fresh take on null safety in the #Java world. Be warned, may contains #Lombok. Happy weekend you all.

Screenshot showing the enforcer plugin breaking the build because Specify 0.3.0 and 1..0.0 don't converge.
While I do like idea about #JSpecify for #Java, here's my reason number one not to ship in one of my libraries as dependency until someone forces me… The annotations' retention policy is runtime time, hence the lib ships with your lib and than this obviously is gonna happen…

🤯 Null pointer exceptions are still around – and still costly for developers.
#JSpecify 1.0 is a new player aiming to fix that, with growing support throughout the #Java ecosystem, including in IntelliJ IDEA.

All you need to do for #Eclipse is configure the #jSpecify annotations into the null-checking capabilities that have existed for ages.

I spoke about Java nullness annotations at a Kotlin conference just to mix things up a bit.

We've all hit NullPointerExceptions. Optional helped with return values, but what about parameters? JSpecify (jspecify.dev) finally gives us framework-agnostic annotations to mark nullable/non-nullable parameters. Static analysis can now catch these issues earlier! #Java #JSpecify

Gradle 9 has been released some days ago and so I have updated the following plugins for compatibility. Please update and report any issues:
- badass-jlink plugin (badass-jlink-plugin.beryx.org/releases/lat...)
- cabe plugin (xzel23.github.io/cabe/cabe.html)
#java #gradle #jlink #jspecify

A really insightful talk about null safety in #Java and #Spring. @seb.deleuze.fr demonstrates how #JSpecify and #NullAway add great value to new and existing projects by turning a design issue of Java into a feature that increases stability and trust in our code bases.

If you are using #jspecify in your #java project, please have a look at the freshly released version 3.3.0 of Cabe that automatically injects null checks for parameters and return values into your code: xzel23.github.io/cabe/cabe.html

![A Java code snippet containing:

I'm definitely not used to reading such array declarations 🙈

#JSpecify annotations are the last annotations I'll ever adapt in the #Java ecosystem. If they don't catch on, nothing ever will until we get null-restricted types in some future JDK.
While the setup of errorprone is a mess (as usual with tools with only one build system in place), it works nice.

J'adore #Kotlin notamment pour le NullSafety.... Mais pourquoi pas avoir ça en Java ? C'est justement le sujet que @seb.deleuze.fr viendra présenter à #MiXiT #tech. Il parlera #JSpecify et #NullAway et comment ce sera au coeur des prochaines versions des frameworks mixitconf.org/2025/null-sa...

Fala galera!
Escrevi um post sobre o JSpecify, uma especificação que traz mais segurança para lidar com null-safety em Java. No post, falo sobre como ele funciona, sua adoção pelo Spring Framework e muito mais.

Now for something completely different.
I work at #Couchbase. We're migrating our #Java SDK to use the #JSpecify nullability annotations. They are phenomenal. It's almost like having Kotlin's nullable types in Java.
