Project Panama

[pschichtel]

It would be nice to have a version of JavaCAN that uses Project Panama for SocketCAN and epoll interaction instead of JNI, making this a pure Java project.

jextract might come in handy for generating the low-level glue-code:

BTW have you thought of giving a try to jnr-ffi or JNA? I think both allow to cut JNI part with some performance sacrifices. I saw it used with dbus (for unix sockets) and systemd (to call its library). Both work with present releases of JVM.

Yes, both would work but face the exact same challenge as project panama.

labeling this for the next major version. I don't think it makes sense to do this without rethinking some API decisions.

Java 22 makes this Project Panama stable: https://openjdk.org/projects/jdk/22/

Java 25 (first LTS to include panama) will be released this september, that might be time to revisit this.
