Pi4j and Eclipse : Possible cause: can't load ARM .so on a AARCH64 platform

[andiriese]

Hello
I'm trying to move my JAVA-pi4j-project from Raspberry Pi 3B to Raspberry Pi 4, 64 Bit, Aarch64
I'm using eclipse.
The java-files are compiling, but after start running I get the following message:

kt. 15, 2024 2:45:47 PM com.pi4j.util.NativeLibraryLoader load
SCHWERWIEGEND: Unable to load [libpi4j.so] using path: [/lib/raspberrypi/dynamic/libpi4j.so]
java.lang.UnsatisfiedLinkError: /tmp/libpi4j13390875237928105628.so: /tmp/libpi4j13390875237928105628.so: falsche ELF-Klasse: ELFCLASS32 (Possible cause: can't load ARM .so on a AARCH64 platform)
at java.base/jdk.internal.loader.NativeLibraries.load(Native Method)
...

I guess, I'm using the wrong library. When I tried to install another one, I got compile-errors like "GpioPinDigitalStateChangeEvent cannot be resolved to a type".

I have no idea, what to do now. Can anyone help me?
