How to Use the Foreign Function API in Java 22 to Call C Libraries

What I'm missing is a model for building/distributing those C libraries with a java application.
Every ffi example I've found seem to operate on the assumption that you want to invoke syscalls or libc, which (with possibly the exception of like madvise and aioring) Java already mostly has decent facilities to interact with even without native calls.
Native libraries are typically packaged inside a jar so that everything works over the existing build and dependency management systems.
For example, each these jars named "native-$os-$arch.jar" contain a .dll/.so/.dylib: https://repo1.maven.org/maven2/com/aayushatharva/brotli4j/
JNA will extract the appropriate native library (using os.name and os.arch system properties), save the library to a temp file, then load it.
> JNA will extract the appropriate native library ..., save the library to a temp file, then load it.
FYI: JNA = Java Native Access project: https://github.com/java-native-access/jna
