This is a major change: "After JDK 9 we'll open-source the commercial features in order to make the OpenJDK builds more attractive to developers and to reduce the differences between those builds " http://mail.openjdk.java.net/pipermail/discuss/2017-September/004281.html http://mail.openjdk.java.net/pipermail/discuss/2017-Septembe... Java Flight Recorder will be open source.

To be honest I didn't even know what Java Flight Recorder was - and I've been doing Java, Clojure and Kotlin for a number of years. I don't see this being a major change for those that have always been on OpenJDK

  I use Java since its introduction in 1996, never installed OpenJDK other than when it came by default on some random Linux distribution. Java Flight Recorder and Visual VM are great tools, only matched by .NET ones to monitor application performance.

This is actually a huge change for operations / devops. JFR is the only tooling out there today that can accurately and safely gather important performance metrics from the JVM in a low impact manner. All other APM vendors like ourselves (jClarity) have to perform hacks of some sort to try and emulate JFR's capabilities. This high quality data source is something that our engineering team is very excited to have opened up!
