Eclipse Mission Control

Parent Project

Eclipse Adoptium®

Proposal State

Created

Background

For 2+ years, AdoptOpenJDK has produced a build of JDK Mission Control. Not only is this build promoted by the OpenJDK JMC upstream project (https://github.com/openjdk/jmc#adoptopenjdk) it's also been distributed via the Eclipse Marketplace for some time (https://marketplace.eclipse.org/content/java-mission-control)

Now that AdoptOpenJDK has moved its OpenJDK distribution to the Eclipse Foundation in the form of Temurin, it makes sense to bring the JMC builds over into a subproject and produce an official Eclipse Mission Control release that can be used by all distributions in the Adoptium Marketplace.

Scope

The Eclipse Mission Control project builds and distributes Adoptium-branded binaries of OpenJDK JMC Mission Control

Description

Eclipse Mission Control enables you to monitor and manage Java applications without introducing the performance overhead normally associated with these types of tools. It uses data collected for normal adaptive dynamic optimization of the Java Virtual Machine (JVM). Besides minimizing the performance overhead, this approach eliminates the problem of the observer effect, which occurs when monitoring tools alter the execution characteristics of the system.

Licenses

Apache License, Version 2.0

Legal Issues

Source code overrides repo uses the Apache License, Version 2.0. This repo is moving from the AdoptOpenJDK into Eclipse Foundation.

JDK Mission Control is built using source from https://github.com/openjdk/jmc. While we don't need to to mirror this repo to the Adoptium project, the builds of Eclipse Mission Control that we ship will be shipped under the The Universal Permissive License (UPL), Version 1.0 (see https://github.com/openjdk/jmc/blob/master/license/LICENSE.txt)

Why Here?

Mission Control was being built at AdoptOpenJDK, this ties in with the move of several other subprojects.

Project Scheduling

Initial contribution can be made soon after the project acceptance.
