Every new JDK, we get new JFR events. Checkout the new event selector buttons in my JFR event collection (sap.github.io/SapMachine/jfr…) to find all events added since the last LTS and in every specific JDK. Thanks @gunnarmorling for suggesting this feature :)

Calling native code from Java has never been easier: With Project Panama, you can call native functions directly. Read more on this in my latest blog post mostlynerdless.de/blog/2023/12/1…

The new release of my IntelliJ profiler plugin has support for profiling Maven goals like "spring-boot:run" and @QuarkusIO. The plugin is alive and thriving. Read more on the release at mostlynerdless.de/blog/2023/12/0…

Some JFR events have fake end times (that are equal to the start time). With the new release of sapmachine.io/jfrevents/, I decided to hide them. So no more confusion about ExecutionSample's duration. It has none :)
