After investigation we have been able to ascertain that the root cause of the issue lies within the zlib that's shipped on macos aarch64 systems. The complete details about that issue is available at https://bugs.openjdk.java.net/browse/JDK-8282954.

Given the nature of that issue, we don't have a timeline on when/if the solution for that will be available. Until that time, at least, the proposal is to use bundled zlib (which doesn't reproduce those failures) by default on macos aarch64.
