Marcus is the project lead for the Open JDK JMC project. Once upon the time he co-founded Appeal, the company creating the JRockit JVM.
Since JDK 14, there is a new kid on the block – Java Flight Recorder streaming, which enables developers to subscribe to JFR data.
It is a feature allowing a developer to subscribe to select JFR data and to decide what to do with that data in the host process. JFR events can also be consumed from a separate process by pointing to the file repo of a separate JVM process – the mechanism is the same.Marcus Hirt
