Btw, the original structure of sevenzipjbindingLinuxArmVersion.jar is:
- Linux-arm
- Linux-arm2
- Linux-arm3
- Linux-armpi
- Linux-armpi2
- META-INF
- sevenzipjbinding-platforms.properties

I now found out the files inside the "Linux" folders are actually different and I'm not sure if the files in Linux-arm work or when this path is normally used. From what I've read my version should at least work with Raspi 3 and even 3 B+. Depending file-size Linux-arm2 and Linux-armpi2 contents have the same file-size.

I will add an even newer version (1602) later, maybe I can fix errors this way.
