Virtual threads are available as a preview feature in JDK 19 and will come out of preview in JDK 21 (https://openjdk.org/jeps/444). It would be nice to be able to use them with Caffeine without inc...
I've added a new custom base image for Java 21 on Lambda to complement the community base images already available for Java 17, Java 18, Java 19, and Java 20. You can find the images on the ECR Public Gallery and DockerHub and the source code on GitHub. Java 21 is an LTS release with
Now that Java 21 is features complete (Rampdown Phase Two at the day of writing), it’s time to walk through all the functionalities that bring to us, developers, this new version. This article is part of a series on what’s new on the last versions of Java, for those who wants to read the others,
Java is constantly evolving with ever increasing performance. JDK 24 comes with significant performance improvements compared to previous versions including improved virtual thread handling, reduced startup time, optimized FFM memory bulk operations…
Not all Java releases receive the same attention from the community. The ones marked as “LTS” have a much higher chance of broad adoption (even if many of us don’t fully understand what the “LTS” means). This alone makes the recently released Java 21 a serious contender. I believe it’s the most influential Java release since Java 8. Just not all of its groundbreaking aspects are already evident to everybody… Let me explain what makes this release so promising.
A blog about Garbage Collection, OpenJDK and Java.
These blogs cover what I’ve learned so far, and I’ll continue to add more as I explore new topics.
Fixing common Java anti-patterns took an app from 1,198ms to 239ms. Eight patterns that compile fine and pass code review but silently drain CPU and balloon heap, with benchmarks and code fixes for each

JDK 21 is almost too good to be true: It finalizes virtual threads, sequenced collections, generational ZGC, and the pattern matching basics; and evolves and introduces over half a dozen other features.
A couple of years ago I wrote a post about the GC progress between JDK 8 and JDK 17 for our three main GCs. With the JDK 21 release this fall, we now have a new LTS release to benchmark and generate some GC performance charts for. JDK 21 and the other releases since JDK 17 have delivered a set of noteworthy features such as Virtual Threads, Pattern Matching for switch and Generational ZGC. Let’s see how it performs.
Java 21 is available today, and it’s quite the update. It brings us 15 (!) JEPS, finalizing features like Record Patterns & Virtual Threads and previewing new ones like String Templates. This blog post has all the info!
Java 24 rolls out today, and it brings a diverse set of features. For example, compact object headers bring better performance, and various security features have been added. Or how about the eagerly-awaited solution to virtual thread pinning? This post has all the info!
Goroutines are the single feature that distinguishes Go from other languages. They look very much like threads, but they are cheap to create and manage. Go's runtime schedules goroutines onto real threads efficiently so you can easily create lots of goroutines.

Just few days left until Java 21 is generally available (September 19, 2023). I've read and collected resources which discuss all the features which 21 will bring.
Lately, there has been a lot of excitement around Durable Execution (DE) engines. The basic idea of DE is to take (potentially long-running) multi-step workflows, such as processing a purchase order …
