Java 26: HTTP/3, Valhalla & G1 GC Upgrades

Java 26 dropped. And yes, the Applet is finally, officially, permanently dead. (Take a moment. You deserve it.) JDK 26 ships 10 finalized JEPs that actually matter: → Native HTTP/3 support in HttpClient, no third-party libs needed → Ahead-of-time object caching for faster startup (any GC, including ZGC) → G1 GC throughput improvements via reduced sync overhead → PEM encoding for post-quantum cryptography readiness. That HTTP/3 item is bigger than it sounds. First-class HTTP/3 in the standard library means one less dependency, one fewer CVE to chase, and better performance on lossy connections, out of the box. The real story? Java keeps evolving, and faster than the "Java is dead" crowd expected. At HaloTechLabs, we have been building Java-based systems for 15+ years. The language we ship today barely resembles what we wrote in 2010. Pattern matching. Records. Virtual threads. Sealed classes. And now HTTP/3 and AOT caching. The ecosystem did not stagnate. It matured. RIP to the Applet. You were a lesson we all needed. Are you planning to migrate to JDK 26, or waiting for the next LTS? #Java #JDK26 #SoftwareDevelopment #BackendEngineering #HaloTechLabs

🔮Java is evolving… but not in the way most developers think JDK 26 doesn’t introduce "Attractive" features It fixes some of Java’s oldest problems 👇 🧵 Thread management → Structured Concurrency 🧠 ThreadLocal → Scoped Values ⚡ Heavy threads → Virtual Threads This is not just improvement… This is a shift in how we write Java code. Rather than "what’s new", its important to understand what's improved!!! So, the real question should be: 👉 What actually changed from JDK 21 → 25 → 26? 👉 What problems are being solved? 👉 And how does it impact real-world code? In this blog, I broke it down with: ✔ Clear timelines (when features were introduced) ✔ Before vs After comparisons ✔ Impact of the change 👉 Read the full breakdown here: https://lnkd.in/dhqZ2ziy #Java #JDK26 #JavaDevelopment #BackendDevelopment #Concurrency #SoftwareEngineering #JavaLoom #Programming #Developers

Java 17 brought major improvements for modern application development, and it’s a great step forward for building scalable enterprise systems. 🚀 Some standout features I really like: ✅ Sealed Classes – Better control over inheritance and cleaner domain models ✅ Pattern Matching for switch (preview) – Cleaner and more readable logic ✅ Records – Less boilerplate for data carrier classes ✅ Enhanced Random Generator API – Better flexibility for random values ✅ Strong encapsulation of JDK internals – More secure and maintainable apps ✅ Long-Term Support (LTS) – Stability for enterprise production systems Why it matters: 🔹 Better performance 🔹 Cleaner code 🔹 Improved security 🔹 Modern language enhancements 🔹 Ideal for upgrading legacy systems Recently, many organizations are upgrading older Java versions to Java 17 to gain long-term support and modern capabilities.

Am I the only one feeling more and more.... idk, lured by Java, those days? Claude takes care of the annoying bits, you get to enjoy the incredible ecosystem it has built over the years... I just saw that Google released "ADK for Java 1.0" last week (Agent Development Kit, basically an SDK to run agents and use all the Google services/models easily), and, uh... idk, one of the major downsides of Java has always been its verbosity... which Claude now takes care of. Java, here I shyly come-ish? I don't wanna admit this to myself.

By recently working with Java, I asked myself: 4GB for heap memory and vm still crashing during unit tests? I believe this turned into something common to Java devs, I mean, not the crash, but reserve 4GB to the app to run. The whole sort of boxing, garbage collection and syntax sugar available on Java, made language more easier over the time, but also made software produced by it less efficient to deal with actual hardware. Java should be consuming less hardware, not more. I decided to focus on rust because he has a more honest approach on how tech is evolving. #rust #java #programming #memory #hardware #tech #performance

💥 If you face this Android build error: jlink executable does not exist Here’s how to solve it 👇 🔍 Root cause: Gradle needs jlink (a JDK tool), but it is picking a JRE instead of a JDK. 👉 Key difference: JDK = has jlink, javac JRE = only for running Java (no build tools) ⚠️ Common scenario: toolchainVersion=21 → Gradle looks for Java 21 System picks a JRE (like VS Code extension JRE) org.gradle.java.home points to a different JDK (e.g., 17) 👉 Result: mismatch + missing jlink = build failure ✅ Fix: Option 1 (simple & stable): Set: toolchainVersion=17 Ensure: org.gradle.java.home = path to JDK 17 Option 2: Install full JDK 21 (not JRE) Point Gradle to that JDK #AndroidDevelopment #Java #Gradle #Debugging #SoftwareEngineering #Developers #MobileDevelopment #AndroidDev #Programming #TechTips #BuildInPublic #LearnInPublic #CodingJourney

POST creates. PATCH updates. Simple. But most devs still confuse them 👇 → POST /users = New resource → PATCH /users/123 = Only change what's needed Don't replace the whole object when you only need to fix one field. That's what PATCH is for. Work smarter. Build cleaner APIs. 🔥 ♻️ Save this. 💬 POST or PATCH — which do you reach for first? #RestAPI #Java #BackendDev #SpringBoot #Programming
