Francesco Nigro Tanel Poder 🇺🇦 Jaroslav Bahorik Carlos O'Donell Nitsan "Yak" Wakart tivrfoa Sharing a plot for one such application which saw a 42% reduction in native memory usage after setting MALLOC_ARENA_MAX to a lower value (16). Most Java applications don't do a lot of explicit native memory allocations and such low values work very well in practice.

New on our blog: The #OpenTelemetry #SpringBoot starter is now stable buff.ly/4gI5Xxb

We're excited to contribute to the #OpenTelemetry #SpringBoot starter to help customers using Spring Boot GraalVM native image applications. Learn how to observe your Spring Boot and Quarkus native image applications on Azure: learn.microsoft.com/azure/azure-mo…

Thank you! Аlina Yurenko 🇺🇦 Fabio Niephaus Thomas Wuerthinger Jean Bisutti Bruno Baptista Martijn Verburg ([email protected]) Julien Dubois John Papa Bruno Borges I couldn't be more excited. We have lots of opportunities for GraalVM on Microsoft Azure and VSCode Java! Java at Microsoft Aki 💙💛 NickZhu

Initial support for jcmd is going to land in @GraalVM Native Image 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! PR at github.com/oracle/graal/p…

Reducing your minor collections to less than once an hour can result in more full GCs, which is counterintuitive. buff.ly/3Cv5Kxz

You can now have OpenTelemetry traces, logs and metrics on Quarkus native applications deployed to Azure! x.com/brunobat_/stat…

That’s a wrap on our #IntelliJIDEALivestream! 🎬 Huge thanks to Dmitry Chuyko and Anton Arhipov for an insightful session on debugging GraalVM Native Images with IntelliJ IDEA. Missed it? Watch the full recording on YouTube! youtube.com/live/St68kE-Vt…

"Look ma, no hands!" Looks like it is relatively easy to put Leyden JVM into AOT-only mode without significant loss of peak performance after a good training run. No (re-)compilations in logs, no compiler threads active, run only the code we brought from the CDS!

JCrete® has the wonderful "problem" of an amazing location and super people, plus we limit attendance numbers to keep the spirit of the Unconference. We have a small number of seats that people can get through our lottery system. Please see jcrete.org for link.

I love just how free the new AOT cache is! For a sample Quarkus application, normal startup time was around 400ms on my machine (JDK 24 EA). When using the new AOT cache feature with JDK 24, the application starts in around 270ms. And all that without a training run!

#JAlba is happening again in 3 months, registration is open! It will be our 6th edition, don't miss out on attending the #Java #unconference in Edinburgh Scotland, created on the model of #JCrete. Come and meet #Java champions and experts. Register now: jalba.scot

On my environment, startup time of each configuration is listed below. Native < CRaC < AOT Cache (JEP 483) < C1 only < jlink and no optimization

Hej Stefan Johansson! Regarding what we talked about at JavaOne, this might help: github.com/openjdk/jmc/pu…

TIL: since jdk22 you can use the JVM option -XX:LogClassLoadingCauseFor=com.mycompany.MyClass in conjunction with -Xlog:class+load+cause* to find out the stacktrace that triggers the load of the specify class. see github.com/openjdk/jdk/pu…

you can also use the JFR event ClassLoad that record the stacktrace at the moment the class is loaded.
