I don’t know what flavors you are looking to support but there seems to be somewhat different issues on a Raspberry Pi. I was just trying to use jpackage there.
I am getting errors like the command dpkg -S /lib/aarch64-linux-gnu/libXau.so <http://libxau.so/>.6 The file isn’t found These actually appear to have entries in /usr/lib/aarch64-linux-gnu Which in turn appear to be symbolic links like… /usr/lib/aarch64-linux-gnu/libXau.so <http://libxau.so/>.6 -> libXau.so <http://libxau.so/>.6.0.0 I am thinking I could try making symbolic links as a workaround myself.
