@bashor after some debugging, I was able to run wasmer-java from IntelliJ on Mac OS X. I had to add:

-Dos.arch=amd64

To VM Options under Run/Debug Configurations for my project.

As far as I can tell there was a recent change that changed wasmer-jni-x86_64-darwin-....jar to wasmer-jni-amd64-darwin-....jar, because of this change during startup the linker can’t find the right native lib.

Please let me know if this helps.
