Are your enterprise applications still running on older versions of Java and Spring Boot? With Java 8 and Spring Boot 1.x/2.x reaching end of life, challenges around performance, security, and scalability are only increasing. Our perspective paper explores how iRenew’s semi-automated approach helps enterprises modernize these applications, improving performance, reducing technical debt, and accelerating time to market. With net efficiency gains of 11%–20% across discovery, refactoring, and testing, iRenew makes modernization faster and smarter. Explore our latest perspective paper playbook on the application modernization journey, including key phases, measurable benefits, and a real-world case study. https://lnkd.in/gw5vnfRf #IrisSoftware #PerspectivePaper #Java #SpringBoot #iRenew

Modernization is no longer a choice — it’s a catalyst for transformation. Across industries — especially insurance — legacy platforms built on older Java and Spring Boot versions are slowing innovation and exposing enterprises to security and scalability risks. At Iris Software, we’re helping organizations modernize smarter with iRenew, our semi-automated modernization framework that: ⚙️ Accelerates discovery, refactoring, and testing 📉 Reduces technical debt and operational risk 🚀 Delivers 11–20% efficiency gains across modernization phases This isn’t just about technology upgrades — it’s about building the agility to launch new products faster, personalize customer experiences, and stay competitive in a digital-first world.

Skimmed this handy roundup of Java 25—and it’s a strong LTS jump for everyday coding. Record patterns, sequenced collections, and (preview) string templates clean up routine code, while module import declarations + compact source files cut boilerplate; on the runtime side, structured concurrency, scoped values, and new JFR profiling round out the upgrade. If you’re still on 21 LTS, which feature would tip you to 25 first? #womenwhocode #softwaredeveloper #softwareengineer https://lnkd.in/ep_8qpP3

🚀 Java 25 is here – and it’s a game-changer! After years of working with Java 21, I was exploring Java 25, and wow – the improvements are tangible. IMO, the highlights are: ✨ Sub-millisecond Garbage Collection (GC) pauses– with enhanced ZGC and Generational Shenandoah, application would feel snappier, latency drops, and the responsiveness boost would be noticeable even under load. ✨ Structured concurrency - Being a preview on 21, now it’s fully production ready simplifying multithreading and error handling. ✨ Data crunching made easy - Stream gatherers enabling massive parallel aggregation. Lower heap allocation in Map.ofEntries(). More efficient memory usage in maps and sets. For anyone still on Java 21, upgrading isn’t just about keeping up – it’s about writing faster, more resilient, and future-ready applications.

🚀 Meet Java 25 (LTS): Why it’s worth upgrading now The latest Long-Term-Support release of Java 25 (LTS) brings a new level of performance, clarity, and modernity to enterprise applications. If your systems still run on Java 17 or 21, it’s the perfect moment to modernize. ✅ Key Benefits of Java 25 Long-Term Support (LTS): stability and reliability for production. Enhanced language productivity: “Compact Source Files,” instance main methods, flexible constructors, and module imports reduce boilerplate. Modern runtime and GC: “Compact Object Headers,” “Ahead-of-Time Profiling,” and the new Generational Shenandoah GC deliver faster startup and smaller memory footprint. Structured Concurrency (Preview): simplifies multithreading and parallel execution. Example — Primitive Pattern Matching (JEP 507) Object obj = ...; if (obj instanceof int i) {   System.out.println("It's an int: " + i); } else if (obj instanceof double d) {   System.out.println("It's a double: " + d); } Or using a switch: switch (obj) {   case int i -> System.out.println("int value: " + i);   case double d -> System.out.println("double value: " + d);   default -> System.out.println("Other type"); } 🔍 Why it’s better than previous versions Earlier releases only supported pattern matching for reference types, forcing manual casts for primitives. Java 25 introduces pattern matching for primitive types — cleaner, safer, and faster code for math-intensive and data-heavy apps. Combined with runtime optimizations and new GC enhancements, it offers higher performance with less memory usage. 🎯 Final Thought Java 25 (LTS) is not just an update — it’s a bridge to the future of enterprise Java. Fewer lines of code, faster execution, better scalability, and a cleaner language design. If you’re planning a migration strategy, this is the version to aim for. #Java #Java25 #SoftwareEngineering #Innovation #LTS #Programming #Technology

LTS versions are important — they’re stable, production-ready, and supported for years. With Java 25, the language takes another big step toward being simpler, faster, and more modern, while keeping all the power Java is known for. 💡 Over the years, Java has often been called verbose — requiring too much boilerplate for simple tasks. But with Java 25, we’re seeing a more streamlined, developer-friendly experience that boosts productivity and readability. In my latest presentation, I’ve summarized the major features of Java 25 with examples and real-world use cases — perfect for developers looking to stay current with the platform. 👉 For deeper dives, check out the official OpenJDK and Oracle documentation.
