@kou I get an exception when I try to load the M1 version.
It looks like the Jni Loader code is missing an underscore. It is looking
for `aarch64/libarrow_cdata_jni.dylib` when the jar contains
`aarch_64/libarrow_cdata_jni.dylib`
```
Exception in thread "main" java.lang.IllegalStateException: error loading
native libraries: java.io.FileNotFoundException:

I can see in the built jar that there is a
`aarch_64/libarrow_cdata_jni.dylib` but not a `aarch64/libarrow_cdata_jni.dylib`
```
❯ tar tf ~/Downloads/arrow-c-data-11.0.0-SNAPSHOT.jar
