Thanks to @saplabsbg for hosting me and @SweetSapMachine

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/…

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/…

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 :)

I gave my last presentation for this year yesterday at JCon World🚀 It was the 14th presentation at a conference this year, not counting the many user groups. What a year. Thanks to me team @SweetSapMachine for making this possible (see github.com/SAP/SapMachine/wi… for all of them)

Ever wondered how you can extend JFR profiling with your own events? I wrote a short introduction at mostlynerdless.de/blog/2023/… that shows you how to integrate custom events in a fictional Math-as-a-Service server.

Looking forward to speaking there tomorrow and spreading the word (and stickers) about @SweetSapMachine, the best JDK distribution out there :)

In this weeks blog post I'll delve into a bug with the JDWP agent's onthrow option, which prevented users from using the full potential of debugging when a specific exception has been thrown. ... and I fix it :) You can find it at mostlynerdless.de/blog/2023/…

Just updated the JFR event collection (sap.github.io/SapMachine/jfr…). You can find information on new events like JavaAgent, and NativeAgent, and all the others on this website. This is one of the many cool things that we at @SweetSapMachine do for the OpenJDK community :)

Say NO to stack walking in signal handlers. Join me on my journey of taming the Bias: Unbiased Safepoint-Based Stack Walking. Embrace memory allocations, locks, and virtual threads in profiling. @eosterlund_fisk had an idea and I the time mostlynerdless.de/blog/2023/…

I fully reworked my AsyncGetStackTrace idea, with the first blog post today: AsyncGetCallTrace Reworked: Frame by Frame with an Iterative Touch! Read it at mostlynerdless.de/blog/2023/… The second blog post will come in time for the JVMLS committers workshop if anyone is interested.

Have you ever wondered how safepoints are implemented in the OpenJDK? Follow me down the rabbit hole into the inner workings of the JVM at mostlynerdless.de/blog/2023/… P.S.: I found a minor bug in the TemplateInterpreter related to safepoints. Find out which by reading my article :)

Ever wondered what keeps profilers awake at night? Its thoughts on jmethodIds: Let me show you why and how I intend to remedy the situation in my new blog post mostlynerdless.de/blog/2023/…
