Thank you for your proposal. It was a bit unexpected :) We would be happy to
Our mac/aarch64 port is in the R&D phase. At some point, maybe we (OpenJDK
community) will need a project or repo for integration. But having win/aarch64
integrated, it may happen that mac/aarch64 support will be just a series of
considerably isolated changes. An example is "JDK-8250876: Fix issues with
cross-compile on macos" . If all changes will be such self-containing, they
may be reviewed and integrated one-by-one. Probably we won't need a project.
I think this work is blocked by the JEP for the new platform support. I'll
start a discussion email thread for that really soon.
I hope we would be able to collaborate in all of the areas. I expect us to get
soon to the point when we can start reviewing changes made for win/aarch64 and
evaluate how do they fit mac/aarch64.

You all bring your immense knowledge from the AArch32 port, and we welcome you and would like to extend our collaboration on the MacOS port. More specifically, we would like to work with you on the -

Once we have a sponsor, we can send the info out on mailto:announce at openjdk.java.net.
