Bug#1028374: libjna-java: JNA HelloWorld fails on aarch64 (and probably armhf, ppc64el)

[Alexandre Rossi]

Package: libjna-java
Version: 5.12.1-1
Severity: important

Dear Maintainer,

When trying the JNA tutorial Helloworld on aarch64, it fails with the following
error message:

    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)
        at com.sun.jna.Native.loadNativeDispatchLibraryFromClasspath(Native.java:1086)
        at com.sun.jna.Native.loadNativeDispatchLibrary(Native.java:1042)
        at com.sun.jna.Native.<clinit>(Native.java:221)
        at HelloWorld$CLibrary.<clinit>(HelloWorld.java:8)
        at HelloWorld.main(HelloWorld.java:14)

The testcase has been proposed as an autopkgtest:

    https://salsa.debian.org/java-team/libjna-java/-/merge_requests/1

Reading autpkgtest results for davmail[1], it also fails with the same error
on armhf and ppc64el.

I have reproduced in a qemu arm64 image, although reporting this on amd64.

I have tried with -Djava.library.path=/usr/lib/jni but it is not better.

I can rebuild, and test and maybe look into this but would appreciate some guidance.

Thank you,

Alex
