So.. this is it!! https://github.com/apache/activemq-artemis/pull/4363
It is using jitpack.io (Thanks Domenico)... I have created a maven plugin that will install the required library, and the new project ./test/leak-tests is working seamlessly... You just run the test.. and that's it. I have the project hosted at github.com/d-leak/dleak I still need to do some cleanup on the API, and add a README. but the version 0.2 is already functional for what I needed here. Le me know what you guys think of this.. On Wed, Feb 8, 2023 at 5:50 PM Clebert Suconic <clebert.suco...@gmail.com> wrote: > > Actually I misunderstood GitHub packages.
