Spring Boot 4.2.0-M1 just landed — 113 enhancements incl. AMQP 1.0/RabbitMQ support. Worth noting: Boot 4's split into 70+ granular modules keeps paying off here — smaller classpaths, faster AOT/native builds, quicker cold starts in K8s pods. #Java #SpringBoot #CloudNative #Kubernetes
One PostgreSQL rename can break every old Quarkus pod still serving traffic. This tutorial works through the safe Flyway sequence: expand, mixed-version writes, backfill, rollback window, then contract. www.the-main-thread.com/p/quarkus-fl... #Quarkus #Flyway

Ports & adapters isn't architecture theatre. When your domain has no idea whether a request arrived via REST, Kafka or an AI agent, adding a channel is a day's work instead of a rewrite. #Java #SpringBoot #SoftwareArchitecture
Our extension for Claude Code can tell your agent what seems to be wrong with your project from a Spring perspective by deliverung diagnostics information directly to the agent - pretty nice to safe tokens and to enhance the agent with more Spring smartness 😎🥳

„Die beiden hatten nie von DevOps gehört, haben aber in 20 Minuten eine komplett automatisierte Pipeline aufgebaut." Für Goran Vukovic steht das sinnbildlich für ein Jahr ASE Training. In den Gruppen sitzen längst nicht mehr nur Entwickler:innen. 📖 Mehr dazu im Blog: www.innoq.com/de/blog/2026...
Most common Spring Boot on Kubernetes mistake: pointing the liveness probe at /actuator/health. The DB health check lives there. One database hiccup → every pod restarts at once. Spring Boot exposes /health/liveness and /health/readiness separately (probes.enabled). Use them. #Java #Kubernetes
I just learned that Oracle, which is shoveling unbelievable amounts of cash into getting everybody to use LLMs, also has a policy forbidding contributors to OpenJDK from using LLMs to generate code, citing code quality, security, and legal concerns: openjdk.org/legal/ai

US Cloud soon illegal? Trump punches first hole in EU-US Data Deal.
Trump seeks to "paralyze" the "Privacy and Civil Liberties Oversight Board" (PCLOB). A key element of the EU-US data transfer deal ("TADPF") that allows EU-US data flows.
