This is primarily due to the fact that the version of jna

(java_dev) sbesson@Sebastiens-MacBook-Pro ZarrReader % mvn dependency:tree | grep jna
[INFO] |     \- net.java.dev.jna:jna:jar:4.2.2:compile

does not include support for arm64 architecture on OSX

(java_dev) sbesson@Sebastiens-MacBook-Pro ZarrReader % tar tf ~/.m2/repository/net/java/dev/jna/jna/4.2.2/jna-4.2.2.jar | grep darwin
com/sun/jna/darwin/

Locally overriding the jna version to use the most recent release

is sufficient to fix the issue since the JAR includes the libraries for the architecture. Is it worth opening the changes above as a PR for now and/or start engaging the conversation upstream?
