Subject: CFV: New Project: Mission Control

I hereby propose the creation of the Mission Control Project with myself (Marcus Hirt) as the Lead and the HotSpot Group as the sponsoring Group.

In accordance with the OpenJDK guidelines [1], this project will provide a home for the continued development of the JDK Mission Control suite of tools, also known as JMC. JMC is a profiling and diagnostics tools suite for the JVM, primarily targeting systems running in production. JMC also provides independent bundles for parsing Java flight recordings, headless analysis of Java flight recordings, and more.

We are now open-sourcing JMC to help keep the JVM-based languages in the absolute forefront in terms of production time profiling and diagnostics.

Open sourcing the core libraries of JMC enables the Java ecosystem to quickly take advantage of features currently in the process of being open sourced in the JVM, such as the Java Flight Recorder, across all contemporary versions of Java.

Open sourcing the stand alone JMC application will provide the community with a base suite of tooling for advanced JVM features, such as Java Flight Recorder. It will also provide the community with an opportunity to build upon this tooling to, for example, expand the number of IDEs supported, not to mention provide new features and capabilities.

I (Marcus Hirt) am a member of the Java Platform Group at Oracle, and I have been working with Java and JVM technology since the early days of Java. I was one of the founders of Appeal Virtual Machines, and the original team leader of Java Mission Control.

Many people have made significant contributions to Java Mission Control.
Special thanks go out to Klara Ward, Erik Gahlin and Markus Persson who have been around for most of the journey.

The initial Reviewers and Committers will be:

* Marcus Hirt (Reviewer)
* Klara Ward (Reviewer)
* Ola Westin (Reviewer)
* Henrik Dafgård (Reviewer)
* Per Kroon (Reviewer)
* Erik Greijus (Reviewer)
* Erik Gahlin (Reviewer)
* Guru Hb (Committer)
* Suchita Chaturvedi (Committer)
* Sharath Ballal (Committer)
* David Buck (Committer)
* Mario Torres (Committer)

The initial source of this project will be based on the development branch of Mission Control 7. The final development and stabilization of Mission Control 7 will take place in the open. Change review policy will be determined by the Lead and a consensus of Reviewers. Review is expected to be relaxed initially, but made more strict as we get closer to the first release.

The project will host at least the following mailing list:

* jmc-dev for developers

Votes are due by 23:59 CET on Tuesday the 1st of May, 2018.

Only current OpenJDK Members [1] are eligible to vote on this motion.
