In my preparation of my talk @jcon about #JSpecify, I released version 4.0.0 of #Neo4j migrations, fully embracing JSpecify and #NullAway. Null-safety on the Java module path, as it should be. See you next week in Cologne.
https://github.com/michael-simons/neo4j-migrations/releases/tag/4.0.0
This #Maven plugin works as promised, nice:
Finally getting around to updating my $work builds to use #ErrorProne and #NullAway again since updating the builds to modern Java.
Everything works, _exect_ building my custom ErrorProne rules as maven can’t see the jdk.compiler classes needed, even with updating the configuration to open the module etc. hrm
70 % aller Fehler in Java-Produktionscode sind #NullPointerExceptions. Mit #NullAway & #JSpecify lassen sie sich statisch verhindern – ohne große Umbauten. Richard Gross zeigt, wie Teams sicher & schrittweise migrieren.

We’d love to host a talk on #Null Safety with #JSpecify and #NullAway at an upcoming #Java User Group Switzerland meetup, and we’re using the power of our #community to find a #speaker!
Are you working with JSpecify and NullAway and would like to share your experience? Or do you know someone who should definitely talk about this? Then please tag them here or point us in the right direction!
You can submit a proposal via our speaker form or contact us on Mastodon.

[Перевод] Можно просто так взять и добавить поддержку проверки на Null
Команда Spring АйО подготовила перевод статьи о том, как JSpecify наконец превращается из «ещё одного стандарта для библиотек» в рабочую основу null-безопасности для всей Java-экосистемы. IntelliJ IDEA 2025.3 впервые согласовала свои проверки с NullAway, а Spring и JetBrains синхронизировали suppressions и поведение анализаторов. Итог — единый, предсказуемый null-анализ без сотен ложных предупреждений.
„Meine Milliarden-Dollar-Fehlentscheidung“ – so nannte Tony Hoare die Einführung von null. Richard Gross zeigt, wie die Firmen @UberEng & @SpringCentral heute mit #NullAway & #JSpecify eine echte Nullsicherheit erreichen.

I created a toy #Java project using #JSpecify
This is what you can express (among others):
One required argument, one optional argument with optional content.
To check it, you need to have #Nullaway https://codeberg.org/michael-simons/javaspektrum/src/commit/14281628ac054dfcaed2c4e3bf951f3329da6b49/jspecify/pom.xml#L319-L341
Build with mvn package -DwithNullaway, to see compile fail (there's test passing null).
Nullaway and modern Java is fun: https://codeberg.org/michael-simons/javaspektrum/src/commit/14281628ac054dfcaed2c4e3bf951f3329da6b49/jspecify/.mvn/jvm.config#L5-L12
Also added #Kotlin code: You can remove the package, and see how it affects what Kotlin sees.
Great discussion
