> Recently as trying to upgrade commons-crypto from 1.1.0 to 1.2.0 in Spark 
> (SPARK-45617), got the following error in one test:
> ```
> [info]   Cause: java.security.GeneralSecurityException: Native library is not 
> loaded

> I did a quick check. commons-crypto-1.2.0.jar only contain x86_64 Mac native 
> library, it doesn't provide pre-built native library for Apple Silicon.
> But I also checked commons-crypto-1.1.0.jar which Spark uses currently. It 
> also doesn't provide native library for Apple Silicon.
> Since they both don't contain native library for Apple Silicon, why 
> commons-crypto-1.2.0 doesn't work and what makes the difference between 
> commons-crypto-1.1.0 and commons-crypto-1.2.0?
