OpenJdk was ported to windows/aarch64 by Microsoft in JEP 388: https://openjdk.org/jeps/388 If there’s any issue with IntelliJ it’s a Jetbrains problem, not a jdk one.

I have to imagine the adventurous that want to use latest JDK and can’t download alternative 32 bit JDK will install Linux. I find the whole what will the poor people of other countries do in this thread in poor taste? Those folks are pretty damn ingenious and will find a solution if it’s even a problem. The real pissed off people I think are actually the privileged who are concerned with e waste and have kept their 20 year laptop because old ThinkPads are great or Stallman concerns. Even large gov orgs will not care because ha they are probably running JDK 6 on those machines. More on reddit.com
