OpenJDK 28 EA build 21 (jdk.java.net/28/) is out, with Adaptive Heap Sizing and faster startup for ZGC. IMO this will be huge for reducing memory usage in Java desktop apps like @intellijidea.com and CLI tools where the heap defaults to 25% of RAM. No more -Xmx roulette #jvm #java #kotlin

70 percent of the internet was vulnerable yesterday to very bad security flaws inside a coding language. Turns out, *one volunteer* is mostly responsible for maintaining that code & helping push updates. Yesterday Ondřej Surý saved the internet. So I called him up www.theatlantic.com/technology/2...

This is huge. With AOT, AHS, and the runtime changes coming in 28, it’s going to be a stellar release. Most people don’t realize how amazing the JVM is, and it just keeps getting better - github.com/openjdk/jdk/... #java #jvm

Happy to announce that JEP 546: “Adaptive Heap Sizing for ZGC” and JEP 545: “Faster Startup and Warmup with ZGC” have both been targeted for JDK 28.

Next LTS (JDK 29) is going to be a banger 🔥 Value types, AOT compilation (training runs), Adaptive heap sizing, Structured concurrency, Compact object headers. Can't wait! #jvm #jdk

If you are like me and don’t enjoy configuring JVM heap sizes (e.g. -Xms, -Xmx, -XX:SoftMaxHeapSize) then finally ”JEP 546: Adaptive Heap Sizing for ZGC” just became a candidate JEP: openjdk.org/jeps/546

openjdk.orgJEP 546: Adaptive Heap Sizing for ZGCEnhance the Z Garbage Collector (ZGC) to adaptively adjust the size of the heap based on the resources available, the application's needs, and the needs of neighboring applications contending for the same resources.

Something big might happen to the Kotlin Multiplatform Ecosystem 👀 We were never too happy about how Kotlin publishes and resolves KMP libraries. It takes up significantly more space than it has to, produces a ton of artifacts and Maven modules, and is just... complex!

Well, #Java 26 is boring, except for the #JVM

Java 26 is here, but it's boring. Nothing really exciting. But that's a good thing, as the boring stability is what made Java successful (co-written with @lutskedev.bsky.social): mostlynerdless.de/blog/2026/03...

The Vite for Kotlin test suite fails with Kotlin 2.3.0 because... Kotlin Wasm has been optimized enough, that the generated Wasm file is so small, that Vite decides to inline it entirely, so there is no visible Wasm in the output
