Bug#1028374: libjna-java: JNA HelloWorld fails on aarch64

[Alexandre Rossi]

Hi,

With -Djna.debug_load.jna=true :

    niol at aarch64:~/libjna-java$ debian/tests/helloworld
    Jan 10, 2023 6:46:28 PM com.sun.jna.Native loadNativeDispatchLibrary
    INFO: Looking in /usr/lib/jni/libjnidispatch.system.so

    Exception in thread "main" java.lang.UnsatisfiedLinkError: Native library (com/sun/jna/linux-aarch64/libjnidispatch.so) not found in resource path (debian/tests:/usr/share/java/jna.jar)

libjna search for libjnidispatch.so as:

    /usr/lib/arm-linux-gnueabi/jni/libjnidispatch.system.so

but it is present on the Debian system as:

    niol at aarch64:~/libjna-java$ dpkg -L libjna-jni | grep libjni
    /usr/lib/aarch64-linux-gnu/jni/libjnidispatch.system.so

I suspect debian/patches/04-load-native-code-from-fs.patch needs fixing.

Cheers,

Alex
