There is too much work to do and not enough time to do it...

If the C2 compiler is intermittently failing to inline code when running a JMH benchmark with the cause "unloaded signature classes", what's the best way to troubleshoot this? I'm not finding a lot of info online.

Mildly hot take: the mailing list system used for JVM/JDK/Java development are antiquated and not a great solution for the purposes they seem to try to serve.

at my employer, moving from 40% to 60% in-office and embracing hot desks, we’ve lost 80% of IC6 (staff / emeritus) people and about 25% of our IC5 (senior principal) in my org.

I gave my notice today to take a full remote job (with a 10% pay cut). They’re down from 6 to 3 SRE and now no manager.

What's the state of the art on measuring power consumption of a Java process?

Thank you! I can confirm I'm seeing the latest now.

I'm so sad I'm not in Barcelona this week for Spring I/O and jealous of all the people who are.

@eddumelendez.bsky.social sorry to ping you here, but I noticed you're a member of SDKMAN and right now it looks like jdk.java.net/25/ EA builds are behind on SDKMAN and I'm not sure where to report it. The latest 25 EA build is 23, but SDKMAN has 16 as the latest: sdkman.io/jdks/open

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/...

Oops. The link to the changelog should be: github.com/micrometer-m...

I haven't worked at an office in several years. Is it no longer considered rude to loudly have online meetings at your desk?

Scoped Values has design choices that restrict certain use cases that were possible with TLs. That was the motivation for seeking real world use. I've made this sample repo demonstrating a limitation when switching threads without direct access to the SV field: github.com/shakuzen/sco...

Anyone have any realistic use of Java's Scoped Values they can share? Yes, I know it's still a preview feature, but I can hope there are some eager people out there.

Last call - CFP for #springio25 closes tonight!
