usb serial not working on droidian arm64 with java program, libNRJavaSerial.so error #233

droidian@Xperia5:/media/droidian$ java -jar /home/droidian/Programmi/Analyzer/Analyzer.jar java.lang.UnsatisfiedLinkError: /tmp/libNRJavaSerial_droidian_0/libNRJavaSerial.so: /tmp/libNRJavaSerial_droidian_0/libNRJavaSerial.so: wrong ELF class: ELFCLASS32 (Possible cause: can't load IA 32 .so on a AARCH64 platform)

after battling with nrjavaserial, ubuntu bugs with nrjavaserial , and java version issues with gradle, I finally built the libNRJavaSerial.so. I searched on droidian for the file, but it only found it in the /tmp/libNRJavaSerial_droidian_0/ libNRJavaSerial.so folder, I tried to replace that but obviously it gets rewritten every time the java program is launched. I don't know how to find the right path to change the file.

i have founded 5 folder with inside libNRJavaSerial celio@Lenovo:~/nrjavaserial/src/main/c/resources/native/linux$ ls ARM_32 ARM_64 PPC x86_32 x86_64 I don't know which file is correct for my purpose. thank.
