We’re excited to share Forrester’s newly released Total Economic Impact™ (TEI) study of IntelliJ IDEA, which JetBrains commissioned to understand how IntelliJ IDEA has delivered value historically and how it continues…
Imagine two threads that never touch each other’s data. No locks, no shared variables, no contention in the code. Yet the program runs several times slower than it should. This is false sharing, and it is one of the few…
with a history of runtimes: every decade a new abstraction arrives that makes software faster to write and slower to run, and Elide is meant to break that pattern. This translates into two concrete aims. The first is…
. Pressler says that since agents write the code, the runtime is what counts. Odersky asks what is left of the language in such a world.
Detroit grew out of an honest post-mortem of Nashorn. Nashorn shipped in Java 8 with ECMAScript 5.1. Then ES2015 arrived and the team chased it for about a year. Then the standard started changing every year, and npm…
in Miami, organized by Moderne and OpenRewrite. My talk is called “Build a Software Factory: An Agentic SDLC on Kubernetes, From Scratch”, and it does what the title says: we put together an agentic delivery pipeline on…
. The plan stays the same: skip JDK 26, 27 and 28 and return to a shared calendar with Java at JDK 29.
is an OpenJDK project that does what a sensible car maker does. It lets a Java program run code written in JavaScript and Python, and the bodywork stays the same: the javax.script API, the one Nashorn used to sit…
OpenJDK puts V8 and CPython inside the JVM, Valhalla pushes a five-preview feature out of JDK 28, GraalVM grows its own java, and a San Francisco team builds a JVM out of the JDK itself.
removes this limitation by adding a bytecode interpreter to the native image. The binary can then load a new class at run time, link it with the classes compiled earlier, and execute it. An interpreter is slow, though,…
OpenJDK puts V8 and CPython inside the JVM, Valhalla pushes a five-preview feature out of JDK 28, GraalVM grows its own java, and a San Francisco team builds a JVM out of the JDK itself.
. He wrote that Detroit might provide the same thing one day, but that it isn’t certain and would take “possibly years”. JVMCI disappeared in JDK 27 anyway. We’ll come back to this in section 3.
with two commands. java HelloWorld.java takes about 220 ms. java -svm HelloWorld.java takes about 55 ms and uses half the memory.
is, according to its README, a hermetic, minimalist Java compiler made only from JDK internals. The madura check command skips code generation and only checks correctness, so it does for Java what cargo check does for…
took place in October at Oracle’s office in Zurich. I wasn’t there, and I found no public write-up apart from one paragraph in Alina Yurenko‘s , which lists attendees from Amazon and Apple to Netflix and Red Hat. So I…
The packaging is the more interesting part. Madura is one file, and the same file runs on macOS, Linux and Windows, on x86-64 and ARM64. The format is called Actually Portable Executable and comes from Justine Tunney‘s…
, and in 25.5 it handles JDK tools such as jstack and keeps compiled code for the next run.
, Kotlin/Wasm is still in beta, and TeaVM and is betting everything on WasmGC in the browser.
produced correct .class files. It has no practical use whatsoever and I’m very glad it exists.
