A map benchmark that only looks up keys that exist can hide a disaster.

ParparVM's HashMap hit in one probe, but a missing key among dense integer keys walked the whole occupied run: 16,742 probes on average at 100,000 entries. Three million containsKey calls took 32.7 s.

Keeping the home slot and changing the collision path to CPython-style perturbed probing cut that to 44.9 ms. Random hits on a large table got slower; the post shows both.

How safe is your Java application, and how safe are the dependencies it ships with? OWASP's Jim Manico has a blunt answer for teams without a security process: you are negligent. Then he explains how to fix that. A very entertaining and informative talk in @foojay podcast 105!

Возможно, Transactional Outbox не так уж и прост?

Я написал transactional outbox для двух своих коммерческих проектов. Подходящих готовых решений на момент написания не было, а CDC на основе лога с Debezium показался слишком тяжёлым для простого требования: сохранить событие вместе с данными и отправить его позже. Само требование появляется потому, что сервис, который меняет базу и затем публикует сообщение, пишет в две системы, а транзакция базы данных покрывает только одну из них. Если процесс умирает между коммитом и публикацией, данные изменились, а никто об этом не узнал. Поменяйте порядок местами - и сообщение уйдёт об изменении, которого не случилось. Паттерн outbox закрывает эту дыру тем, что делает событие частью транзакции. Вместо того чтобы публиковать прямо в брокер, сервис записывает событие в таблицу рядом с бизнесданными, а доставляет его отдельный шаг, позже.

Our Java card classifier was 99.9% sure on the first card, then wrong on the next ones, some at 97.9% sure. It learned from about 30 webcam images per card, and JobRunr ran the training. What would you change first: more images, other lighting or another model?

We could tell you what #JCON EUROPE feels like. Our #community says it better:

"The people. The audience was engaged with the talks, other speakers were great, crew was friendly and helpful. Thanks for having me!"
- Marit van Dijk, #Java Champion

"I really like the aspect of a conference from the community for the community."
- Simon Martinelli, Java Champion, Oracle ACE Pro

#JCON2027 blind tickets: 30% off, until we publish the first speaker.
🎟️ https://2027.europe.jcon.one/tickets

An agent's ticket-search tool needs to describe its search rules, accepted inputs, and result limits.

The Java example returns five summaries and says when more match. I describe context retrieval separately, keeping comment histories out of search.

[recovery mode] Автоматизация релизов Java-монолита в закрытом контуре: замена maven-release-plugin на JGit

Тезис: Как мы автоматизировали подготовку релизов в банке (Java 17, Spring), написали свой плагин для проверки release notes и обошлись без выделенного DevOps-инженера, используя чистый Java-стек в закрытом контуре.

#GenerativeAI #MachineLearning #OpenSource #Micronaut

In `io.github.glaforge:gemini-interactions-api-sdk:2.2.0`, `DecisionParams` offers `.noul()`, `.choice()` & `.score()` builders, and `client.createDecision(params)` returns sealed `NoulAnswer`, `ChoiceAnswer` & `ScoreAnswer` records (plus server routing in `InteractionsHandler`).

Compare both #Micronaut 5 / #Java 25 editions live on #CloudRun:
⚡ CPU (`gemini-decision-1`): https://purrfect-match.cloud.run
🖥️ GPU (`DiffusionGemma`): https://purrfect-match-gpu.cloud.run

Back in September, I deployed `DiffusionGemma` + `djev` on a #CloudRun Blackwell GPU to test "System 1" multimodal classification in Java.

This week Google DeepMind launched #Gemini Decision 1 (`gemini-decision-1`) & the Decisions API (`POST /v1beta/decisions`). I just released v2.2.0 of my Gemini Interactions #Java SDK on Maven Central to support it, & migrated my Purrfect Match demo to run without any GPU! 🧵👇

Thanks to everyone who joined my SALT (formerly Utah JUG) talk, "Software Factories for the Agent Era."

The demo pairs four GitHub Actions checks with GitHub Copilot code review. Two staged pull requests show where checks help and where they can miss a bad change.

The repo includes the Java app, API contract, tests, branch rules, and a guide to replaying the review. A person still approves the merge.

Half my chats with Claude are mostly "Why the f*** have you over complicated this?", especially with Java. It loves to build elaborate objects with `isFor` or some other junk that hides complexity and breaks the readability.

Just call a spade, a spade you crazy machine!

This is what concerns me about the future - new developers not knowing when something *should* be complex, and when it doesn't need to be.

Новая книга по Spring Security. Насколько это актуально сегодня?

Spring Security обладает интересным свойством: подключить его к проекту очень просто, а вот понять, что именно произошло после добавления зависимости, уже не так просто. Вот вы добавили spring-boot-starter-security , и приложение внезапно начало возвращать форму входа. Откуда взялся пользователь? Кто создал цепочку фильтров? Почему один запрос завершается со статусом 401, а другой со статусом 403? Почему после добавления еще одного SecurityFilterChain часть прежних правил будто бы перестала работать? Можно, конечно, каждый раз находить похожий пример и копировать конфигурацию. Иногда это даже будет работать. Проблема начинается тогда, когда поведение фреймворка нужно изменить или когда найденный пример относится к другой версии Spring Security. Главная проблема большинства материалов по Spring Security в том, что они показывают какую-то небольшую часть общей картины, при этом у человека после чтения не остается цельная модель происходящего . С этой точки зрения предлагаю посмотреть на четвертое издание книги Бадра Насслахсена «Spring Security». Русское издание вышло в 2026 году. Это будет небольшая рецензия/обзор книги с моей стороны. Сразу обозначу свою позицию. Я не считаю эту книгу универсальным руководством по безопасности приложений и не думаю, что ее примеры можно бездумно переносить в production. Но как способ систематизировать знания именно по Spring Security она вполне заслуживает внимания . Ниже постараюсь объяснить почему.

Codename One builds Flutter apps from their Dart source by transpiling to Java. Now stack traces name your .dart file and line, and a Java debugger attached to the simulator steps through the Dart. No new debugger: the build rewrites the class files' line tables and adds a JSR-45 source map, the mechanism JSP debugging has used for twenty years.

My article "Modular Java Applications with Apache Maven 4" is out in @javapro.

@ASFMavenProject's Maven 4 introduces the module source hierarchy: several Java modules in one pom.xml — a clean api/core/cli split with real encapsulation, and no multi-module reactor.

Three Java modules, one POM, three JARs. Maven 4 introduces a module source hierarchy that packages each Java module separately, without multiple Maven subprojects.

Gerd Aschemann shows how it works in practice: https://javapro.io/2026/11/12/modular-java-applications-with-apache-maven-4/

We benchmarked OpenJDK AppCDS across Spring Boot, Jenkins & SonarQube on K8s to see if pods become Ready faster after cache-fetching overhead.

The surprise: sequential init containers ate 100% of our JVM gains (~1.75s tax). Pivoting to K8s 1.33+ Image Volumes fixed it, cutting Spring Boot readiness from 5s → 3s with zero code changes.
