Excited to speak at #WasmCon Europe next Monday about bringing #WebAssembly to the JVM ecosystem with @graalvm.org. I’ll demo GraalWasm in a Spring Boot app and show how GraalVM can compile JVM apps to Wasm for browser, mobile, and cloud. Join us! Details: sched.co/2DY2u

WasmGC is coming to GraalWasm, unlocking the power of JVM garbage collectors for #WebAssembly! This will also get GraalWasm a lot closer to implementing the full Wasm 3.0 spec. Join @ssmith.bsky.social and me at @jfokus.se next month to learn more: www.jfokus.se/talks.html?s...

The @kotlinlang.org team at @jetbrains.com is working on a @graalvm.org-compiled kotlinc. Early experiments look very promising: > So far, a native image with PGO offers a properly "warmed-up" kotlinc and with up to 20% more peak throughput. Ticket: youtrack.jetbrains.com/issue/KT-823...

Looks great! I think I found a bug though. If you go straight to a page like sdkman.io/jdks/graal/, I get a broken page:

"Hello from #WebAssembly generated with @graalvm.org!" 👀 (And yes, we can run more than a HelloWorld program 🤓) More at #WasmIO25 tomorrow: 2025.wasm.io/sessions/the...

This is me debugging a Rust library compiled to Wasm and embedded in a @micronautfw.bsky.social microservice in @intellijidea.com: Compile with debug info, enable the Chrome Inspector for #GraalJS and #GraalWasm, and attach to the process. 🤓 Will share more details at #WasmIO later this month!

We just merged the current status of the upcoming JDWP support for @graalvm.org Native Image! 🥳 This will soon provide developers with the same debugging experience they are used to in Java, but for native images! Stay tuned for more details. github.com/oracle/graal...

The free Ampere resources on Oracle Cloud are enough for me to set up even two runners that can build #TruffleSqueak in parallel!

Initial support for jcmd is going to land in #GraalVM Native Image very soon! 🥳 This will bring diagnostics and monitoring of native images even closer to the HotSpot experience. JFR, heap dumps and thread dumps, JMX, and NMT are already available! Pull request at github.com/oracle/graal...
