🎥 New video on the channel from @asm0dey.site! Your Dockerfile may look clean, but is it secure? We break down 8 common Dockerfile mistakes that can increase your production attack surface. Watch now 👇 youtu.be/KKRda0H4wTE #Docker #Containers #DevSecOps #CloudNative

🚨 Hidden Pitfalls of Staying on Free Legacy Oracle JDK Versions 🧵👇

Hardened images vs Distroless containers - What’s your choice? Both aim to reduce attack surface and improve container security, but they solve different problems and come with different tradeoffs. @edelveis.dev breaks it down in this short video preview. #Containers #DevSecOps #Java

Live from @jnationconf.bsky.social and sunny Portugal 🇵🇹☀️ @asm0dey.site and @antonarhipov.bsky.social are all smiles because they just finished their talk: “The Ultimate Showdown of Database Migration Tools”, and the room was PACKED 🔥 Amazing session, amazing crowd, amazing atmosphere. #Java

Our latest research found that 42% of Spring developers have never encountered hardened container images at all. That’s a major knowledge gap as supply chain security and CVE exposure become bigger concerns in production. So we made a quick guide: www.youtube.com/watch?v=Co16... #DevOps #Security

What was it actually like to code Java in 1995? ☕ To celebrate how far Java has come over the last 30 years, our Developer Advocate @asm0dey.site took Java 23 code and rewound it all the way to Java 1. Watch the journey: www.youtube.com/playlist?lis...

We grew up with Java. Some of our engineers remember its very first years, and helped it take its first steps at Sun Microsystems. 31 years later, we’re still building Java runtimes for enterprises and developers around the world. Happy Birthday, Java ☕ #Java #Java31 #OpenJDK

🎥 NEW VIDEO on the channel from @asm0dey.site You don’t need to switch frameworks to learn something new. This time on the channel: @quarkus.io , explained for developers who already know Spring and want to broaden their Java framework knowledge. #Java #Quarkus #Learning

How secure is your Java container? Save this checklist ✅ To help teams improve their security posture, we created a practical container security checklist. How many can you answer YES to? #Java #SpringBoot #Docker #ContainerSecurity #DevSecOps #Security #SBOM #CVE

🍃 The Persistence Heavyweight Championship: JPA vs. jOOQ by @asm0dey.site/ @edelveis.dev @ Spring I/O 2026 ▶️ Video: youtu.be/yAish_3P3-I 🔗 Slides: speakerdeck.com/cat_edelveis... #springio26

We surveyed 250 Spring developers at @springio.net 2026. The results exposed a major blind spot: 64% don’t realize poorly written Dockerfiles can introduce security vulnerabilities. Read full Report: bell-sw.com/spring-conta... #Java #SpringBoot #Docker #ContainerSecurity #DevSecOps #security

Java Streams did not need a method for every use case. They needed an extension point. Stream Gatherers provide built-ins for common stateful ops, plus a way to define your own intermediate ops while staying in the Stream pipeline. Fixed-size batching with windowFixed 👇 Requires Java 24+.

Ten Git commands worth using: git switch, git restore, git stash -p, git add -p, git reflog, git bisect, git worktree, git cherry-pick, git sparse-checkout, and git push --force-with-lease. Walkthrough by @edelveis.dev: youtu.be/Q4M_ape8cM0

New in Java 25: flexible constructor bodies (JEP 513)! You can now validate arguments or do setup work before an explicit constructor invocation – no more boilerplate helper methods.

CVE cleanup never really ends, and treating it like an endless patch queue gets old fast. In her piece for JavaPRO, @edelveis.dev writes about what scales better: hardened images, provenance, SBOMs, scanning, and patch workflows that hold up under constant pressure. javapro.io/2026/04/14/m...

Six minutes on dynamic SQL with Spring Data JPA: Specifications, optional filters, Specification.allOf(...), and the JPA Static Metamodel. By @edelveis.dev: youtu.be/py1dWQLnnxU

Liberica NIK 23.0.12, 23.1.11, and 25.0.3 are out for JDK 17, 21, and 25. These CPU-aligned builds include several security and bug fixes, with eight vulnerabilities fixed across all three releases and one additional issue addressed in the JDK 25 build: bell-sw.com/blog/the-bui...

🧵 THREAD: RestClient vs WebClient vs RestTemplate. These three names get thrown around constantly in Spring discussions, but they are not interchangeable, and choosing the wrong one creates unnecessary complexity fast.

Scoped values were finalized in #Java25. A cleaner alternative to thread-local variables, with bounded lifetime and a strong fit for virtual threads 👇

Many teams build container images component by component and assume the result will be optimal. In his piece for CDO Trends, Dmitry Chuyko explains why that logic often fails for #Java apps and why base image strategy has to be looked at as a whole: www.cdotrends.com/story/4964/7...

A side-by-side comparison of the main OpenJDK distributions in 2026, from Temurin to Liberica, Zulu, Corretto, and others. Support, updates, lifecycle, vendor alignment, and what those differences mean when you are picking a runtime for enterprise workloads. By @edelveis.dev: youtu.be/Ytdo8OGEYFI

A notable JDK 24 change: JEP 486 permanently disables the Security Manager. Starting with JDK 24, enabling it is no longer supported, either at startup or during runtime. Minimal repro 👇

Today at 18:00 CET, Leif Åstrand will build a reactive web app with Spring Boot and Vaadin using only Java. Real-time updates, external services, and UI, with no JavaScript, HTML, or CSS in the stack. Save your spot: bell-sw.com/webinars/rea...

Tomorrow in Lyon, @asm0dey.site is speaking at Lyon JUG on CRaC and near-instant Java startup. 5 ms startup, Spring integration, CRIU vs CRaC, and the real benefits and limits of checkpoint/restore for Java apps. 📅 Apr 28, 19:00–21:00 GMT+2 📍 Lyon More info: www.meetup.com/fr-fr/lyonju...

No single base image wins everywhere. In her new guide for DZone, @edelveis.dev looks at the perks and trade-offs behind lightweight Linux distros for containers and what teams should pay attention to in production: dzone.com/articles/top...

Container security gets discussed at the code level all the time, while the base image quietly keeps shipping most of the problems. Missed DaShaun and @edelveis.dev on hardened images, CVE noise, and why patching in place keeps wasting time? The recording is here: www.youtube.com/live/9Zfo_HA...

Liberica JDK CPU and PSU updates are out for 6, 7, 8, 11, 17, 21, 25, and 26. This release contains 954 fixes and backports overall, with BellSoft contributing to 63 resolved issues across the supported versions. Details: bell-sw.com/blog/liberic... Download: bell-sw.com/pages/downlo...

On April 28, Leif Åstrand will show how to build a reactive web app with Spring Boot and Vaadin using only #Java, covering real-time updates, external services, and UI without dropping into JavaScript, HTML, or CSS. 📅 Apr 28, 18:00 CET Register here: bell-sw.com/webinars/rea...

Tomorrow, @edelveis.dev is speaking at JCON in Cologne with Mission Possible: The 45-Minute Path to Bullet-Proof Java Container Images, shrink, pin, scan, sign. A practical path from messy #Java container images to hardened ones. 📅 Apr 22, 09:00–09:45 📍 Cinema 6

A neat Java idea from JDK 24 preview: JEP 487, Scoped Values. Scoped values aim to make shared immutable context easier to reason about than ThreadLocal, especially in modern concurrent code. Tiny example 👇

This Thursday at #JCON in Cologne, @asm0dey.site is speaking on From Git Panic to Git Zen: With a Little Help from AI. Reflog, bisect, interactive rebase, and how AI + a custom MCP server backend can make advanced Git a lot less painful. 📅 Apr 23, 14:30–15:15 📍 Cinema 7

Amsterdam, yesterday evening 🇳🇱 Dmitry Chuyko spoke at the Amsterdam JUG Meetup at OpenValue on JDK Doping: Performance Gains Without Touching Your Code. Thanks to everyone who joined!

🧵 THREAD: Java Developer Roadmap 2026. If you want a clearer map of what to learn next, this is the sequence that gets people from basics to production: core Java, tools, SQL, Spring, testing, deployment, and concurrency.

Spring I/O is over, and the best part as always was the people. Thanks for the booth chats, the talk questions, the #Java debates, and the good energy all the way through. Until next time 💚

Delivered in JDK 22, JEP 454 gave Java a standard Foreign Function & Memory API. Calling native code no longer has to start with JNI boilerplate. Tiny example 👇

Tomorrow at @springio.net, 15:30 in Track 5: @asm0dey.site and @edelveis.dev present The Persistence Heavyweight Championship: JPA vs. jOOQ 🥊 N+1, Criteria API, code generation, runtime performance, and audience voting after each round. Come help decide who takes the belt!

Missed the buildpacks session with @edelveis.dev and Joe Kutner? The recording is up. Good watch if you want a clearer picture of what gaps buildpacks close and where they make more sense than hand-written Dockerfiles. www.youtube.com/live/x0uLOhh...

Barcelona, day 1 of @springio.net, and we are already at the booth. 😎 Come by for #Java chats, BellSoft Hardened Images, and Liberica JDK, the Java runtime recommended by Spring. Also yes, the Steam Deck raffle is back, and so are the limited-edition shirts! See you there 💚

This Wednesday at @springio.net, 9:00 in Track 5: Dmitry Chuyko on SBOMs and what it takes to make them useful in the real world. CI/CD policies, hardened containers, Kubernetes checks, SPDX vs CycloneDX, and supply chain security that does more than sit in a report. Come catch the talk!

A fresh draft JEP with big day-to-day potential: convenience methods for JSON documents. The idea is JSON parsing in the JDK with low ceremony via the incubating module jdk.incubator.json, so simple lookups can be as short as Json.parse(...).get(...).string(). openjdk.org/jeps/8344154 Tiny example 👇

Setting Xmx is not the same thing as understanding JVM memory. This video with @edelveis.dev breaks down what else eats RAM in a #Java process, which flags matter, and how to tune memory without turning your JVM into a superstition project: youtu.be/wkevk6kYmQY

🧵 THREAD: Docker Container Security Checklist. Most Docker images look fine right up until they hit production. These 13 container image security practices separate something runnable from something you can trust in prod.

☕️ We’re live now at Coffee+Software! @edelveis.dev and @dashaun.com are talking about hardened images, CVE overload, patching churn, and what changes when the base image stops being the main source of work: www.youtube.com/watch?v=9Zfo...

Tomorrow: @edelveis.dev and @dashaun.com on hardened images for #Java services. Less CVE noise, less patching churn, fewer rebuild loops, and a base image that does not create half the problem in the first place. 📅 Thursday at 14:00 CET

One JEP worth revisiting: JEP 485 in JDK 24. It introduced gather(...) to streams, a new intermediate operation for transformations that do not fit neatly into map, filter, or flatMap. Tiny example 👇

🔥 We are live now with @edelveis.dev and Joe Kutner! Buildpacks, Dockerfiles, image creation, maintenance, security, and where buildpacks make life simpler: www.youtube.com/live/x0uLOhh...

What happens when two developers use GitHub Copilot to build the same #Java app live, under quality gates? @rabauer.dev turned his stream with @edelveis.dev into a write-up on what worked, what broke, and which prompting approach held up better once the checks kicked in: rabauer.dev/blog/vibe-co...

Getting the last element of ordered collections in Java used to be awkward, especially with LinkedHashSet. Java 21 changed that with JEP 431, introducing sequenced collections and methods like getFirst(), getLast(), and reversed() for encounter-ordered types. A neat upgrade for everyday code 👇

This Wednesday: @edelveis.dev and Joe Kutner on buildpacks. Why they exist, what they fix, and why they can be a better alternative to Dockerfiles when you want faster, cleaner, more consistent image builds. 📅 Wednesday at 16:00 CET www.youtube.com/live/x0uLOhh...
