File /lib/raspberrypi/dynamic/libpi4j.so was not found in classpath

Using pi4j-core-1.4-20210125.201054-11.jar and getting this:

2021-02-06 23:59:09,356 ERROR [main] c.p.u.NativeLibraryLoader Unable to load [libpi4j.so] using path: [/lib/raspberrypi/dynamic/libpi4j.so]

I can clearly see Gpio.java tries to load this:

    static {
        NativeLibraryLoader.load("libpi4j.so", "pi4j");
        isrCallbacks = new List[46];
    }

which leads to NativeLibraryLoader trying to load /lib/raspberrypi/dynamic/libpi4j.so resource from classpath, but only these two are available: under /lib/raspberrypi/dynamic: libpi4j-armhf.so and libpi4j-aarch64.so. This leads to the exception above.

Alright, I can see it's a regression that was fixed 10 days ago https://github.com/Pi4J/pi4j/commit/806543d1dc7390f8066433ab78ae8edaa127ef83

I don't remember deploying updated 1.4-SNAPSHOT -- so maybe that is why it failed for you. I have deployed new snapshots to the OSS repository based on latest in master branch today.

Thanks!
