Thanks @Per Liden<mailto:per.liden at> for your leadership in getting ZGC to where it's today.

I wish you the best in your future endeavors. I think ZGC will be in great hands with @Stefan Karlsson<mailto:stefan.karlsson at> at the helm!

You have my full support. Thanks both for the great work.

Subject: Resigning as ZGC Project Lead

I hereby resign as ZGC Project Lead.

It has been a super exciting time for me to drive this project from a
proof-of-concept to a state-of-the-art GC that today powers mission
critical workloads around the world. However, I will be taking a step
back from ZGC development to do other things, and so it feels natural to
hand over the project lead role to someone else.

According to the OpenJDK Bylaws [1], a new Project Lead may be nominated
by the Group Leads of a Project’s Sponsoring Groups. Such a nomination
must be approved by a Three-Vote Consensus of these Group Leads. In this
case, that means Vladimir Kozlov from the HotSpot Group appoints a new
Project Lead. I would personally recommend Stefan Karlsson as new
Project Lead. Stefan has played an invaluable role in this project since
its inception and is a natural successor.
