This is my actual collection of ideas from March 2025, when it was unclear whether the updated JFR sampling at safepoints made it into JDK 25. It eventually did, so I scrapped the ideas. But it offers the reader an interesting, unfiltered look into my ideas and thoughts at the time, probably only useful for people who are really into profiling and the OpenJDK. Just be aware that it is therefore a document of its time (March 2025) and doesn’t reflect the actual current implementation. Also, don’t expect any deeper explanations.
