Apple M1:

This Mac j64 fat binary contains both binary for x86_64 and arm64
architectures so that it runs in native arm64 mode on apple M1.  To query
its cpu architecture, type
  9!:56'cpu'
arm64

To force it to run in x86_64 mode on apple M1 via Rosetta 2, type
$ arch x86_64 ./jconsole
  9!:56'cpu'
x86_64

Rosetta 2 doesn’t support avx or avx2.
