Thanks very much for starting the discussion. I'm interested in evaluating the switch from OpenJDK to AdoptOpenJDK. I've been using JDK 8 and 11 hotspot builds from AdoptOpenJDK for many months with very good results.
Several of the OpenJDK providers (Red Hat, Amazon, Azul) seem to be limiting their platform support much more than AdoptOpenJDK does. So long as we can get the platforms we need (Debian, CentOS, UBI), I'm interested in evaluating the change. I thought there were specific barriers that prevent Alpine Linux support, though I see that Azul provides an Alpine Linux build for 8, 11, and 13.
