I cannot currently build this because my libjloda-java is at 0.0+20161018.

You have put the wrong openjfx jar into debian/manifest:

$ jar tf /usr/share/java/openjfx/lib/javafx-mx.jar | grep javafx.geometry
<no output>

$ jar tf /usr/share/java/openjfx/jre/lib/ext/jfxrt.jar | grep javafx.geometry
[...]
javafx/geometry/Insets.class
[...]

This simple patch should work:

diff --git a/debian/manifest b/debian/manifest

If you need more help with this package, please tell me how to get
libjloda-java (>= 0.0+20170502).

Cheers and Best Regards,
