OpenJDK JDK11 not having JMC- Java Mission Controller- FlightRecorder

Tags:

I was hoping JMC would be available with OpenJDK, JDK11 binaries as this has been opensourced from Java 11 by oracle, but could not locate this in Oracle and AdoptOpenJDK Java-11 binaries under bin folder. I have also tried this https://jdk.java.net/jmc/ as some article said its being releases separately. Does anyone know how to get JMC for OpenJDK-11.

Is JMC open source?

JDK Mission Control is an open source tools suite for the Java virtual machine. The tools help finding problems in, and optimizing, programs running on the JVM in production. JDK Mission Control supports OpenJDK 11 (and above) and Oracle JDK 7u40 (and above).

Is JMC part of JDK?

Is Jfr available for OpenJDK?

1 Answer. Show activity on this post. JFR was a commercial feature in Oracle Java up to Java 1.8 that needed to be specially enabled (using -XX:+UnlockCommercialFeatures ). With Java 11 and later it is no longer a commercial feature so you don't need this flag.

Is Jfr open source?

Now, the JFR is open source in OpenJDK 11, and available in the OpenJDK11/bin folder; while the JMC is not part of the JDK anymore, we can download here.

I am editing this answer since builds are now available, and have been available, from multiple vendors for quite some time. The list is available in the readme for the JMC GitHub repo:

https://github.com/openjdk/jmc

Don't forget to give the project a star if you like it! :)

Here is the original answer:

Normally the builds will be available here: https://jdk.java.net/jmc/

See http://hirt.se/blog/?p=1007 for more information on the new delivery format.

The builds have been (temporarily) pulled because a switch from the old javax.mail coordinates to the new coordinates at jakarta-ee has not yet gotten the proper third-party approval. A new build, with plenty of fixes and with all the approvals properly in place (or a revert of the change), should be along within the next few weeks.

Up until then it is possible (also not hard) to build JMC 7, by pulling the official JMC repo from here: https://hg.openjdk.java.net/jmc/jmc7/

You can also build and pull the mainline mirror from the inofficial GitHub repo: https://github.com/JDKMissionControl/jmc

For more information on building JMC, see: http://hirt.se/blog/?p=947 (or simply read the README.md in the repository root)

Good luck!
