It seems that quite some dependencies like for networking, databases etc use natively build code internally using JNI. If those new targets like Mac arm64 are not added, those dependencies don't load. I can remember for example the Google Protobuf JVM package which uses the C++ written Protobuf library internally. It took quite some time before people inside Google had M1 machines and were building the JVM library too for M1.

It seems that those CPU architectures indeed sneak back through a back door... The same on Android, there you have also many libraries which need to be build and published for specific architectures. But luckily new architectures are not added regularly.
