Are you aware aware that the commit for 8284161 https://github.com/openjdk/jdk/pull/8166 will require changes to your port? Will you be able to fix it in time for JDK 19? You don't have to implement virtual threads: it may only be necessary to stub some things out, but there may be other issues as well.
Please check, and please shout out if you don't expect to get your port working in time for JDK 19. -- Andrew Haley (he/him) Java Platform Lead Engineer Red Hat UK Ltd. <https://www.redhat.com> https://keybase.io/andrewhaley EAC8 43EB D3EF DB98 CC77 2FAD A5CD 6035 332F A671
