It works on OpenJDK, Oracle (going back to before JMC days) and Zing (recent
releases), though it does rely on an unofficial profiling API.It does not cover
anything else th
I agree with the need/wish for a common way to get such information from
JVMs. A common & standard way for JVMs and OpenJDK to provide event tracing
as well as low-runtime-cost JVM instrumentation details (for information no

scenario (as) commonly used with JFR.
Basically, using JFR for production [currently at least] requires a
commercial Java SE Advanced license. How/if thi
