Free updates for Java 21 end Sept 2026. This white paper breaks down  the factors that may delay your ability to adopt Java 25 even as Oracle ramps up its Java audits, how Oracle’s roadmap could cost your organization millions and what you can do to regain control of your Java strategy. https://lnkd.in/ga7-Pezk   #Java21 #JDK21 #Java #OracleJava

Oracle’s removal of the Graal JIT compiler is a big shift for Java performance. Azul Platform Prime now stands alone for teams that need low latency, high throughput, and fast warm-up. If performance matters, this blog is well worth your time. #Java #JVM #JavaPerformance

“Why Upgrade to Java SE 25 LTS Now” “If you’re still on Java 17/21 and delaying an upgrade, here’s something to consider…” - The latest Java LTS release, Java SE 25, was made generally available on September 16, 2025. - It introduces 18 new JEPs, including features like structured concurrency, improved JFR CPU-time profiling for Linux, ahead-of-time (AOT) cache improvements, and more. - From a backend developer’s perspective (like me, working on microservices with Spring Boot + Hibernate + MySQL): - Structured concurrency can simplify our threading code for service calls (especially in async or reactive flows) AOT & improved profiling help improve startup time and performance for Spring Boot services Upgrading early means less painful migration in future, more “future proof” “Here’s my plan for moving our banking-app backend (built with Java 21 + Spring Boot) to Java SE 25 — start with test environment, check dependencies (Hibernate, etc), evaluate performance gain, then rollout.” Why this works: - Shows you are up to date with platform changes - Positions you as someone thinking about architecture & performance - Ties into your backend developer focus #Java, #JDK25, #BackendDev, #SpringBoot.

🚀 Java 25 is Here! The latest Java SE 25 (LTS) is out — continuing Java’s fast 6-month release cycle. ✨ Key highlights: Virtual Threads & Structured Concurrency 🧵 Performance boosts & memory improvements ⚡ Stronger support for modern frameworks like Spring Boot 3.x 🌱 💡 Why it matters: Upgrade to Java 25 (or 21 LTS) for better speed, scalability, and future-ready features — especially if you’re building AI-driven or microservice apps. #Java #SpringBoot #Developers #Java25 #Programming #TechUpdate

Spring Framework 7 is set to bring exciting improvements for Java developers. This release focuses on making applications more resilient with built-in retry and concurrency limits. The new version also introduces elegant API versioning for easier management of evolving APIs. Developers will benefit from programmatic bean registration which simplifies complex bean configurations. Other highlights include enhancements to HTTP, JMS, and JDBC clients, better support for modern Java 24 features like virtual threads, and cloud-native improvements with better Docker and OpenTelemetry integration. Testing becomes smarter with the ability to pause unused application contexts to save resources. Spring Framework 7 aligns well with modern ecosystems such as Kotlin 2.2 and GraalVM 25, helping developers build faster, scalable, and more fault-tolerant applications easily. The future of Spring looks robust and developer-friendly! #SpringFramework7 #JavaDevelopment #SpringBoot4 #Resilience #CloudNative #Java24 #APIversioning #SoftwareEngineering
