JDK Mission Control supports OpenJDK 11 (and above) and Oracle JDK 7u40 (and above). JDK Mission Control primarily consists of the following tools:
JDK Flight Recorder is an event recorder built into the OpenJDK [1] Java virtual machine. It can be thought of as the software equivalent of a Data Flight Recorder (Black Box) in a commercial aircraft. It captures information about the JVM itself, and the application running in the JVM. There is a wide variety of data captured, for example ...

Flight controllers are personnel who aid space flight by working in mission control centers such as NASA's Christopher C. Kraft Jr. Mission Control Center or ESA's European Space Operations Centre. Flight controllers work at computer consoles and use telemetry to monitor various technical aspects of a space mission in real-time .
A JCP representative (far right) speaks to the trade press during a panel discussion at the JavaOne conference in 2012. The JCP's executive board has been characterized as a "rubber stamp organization" since Oracle acquired Sun Microsystems (the original developer of the Java language).
