Sweethome 3s in Linux Mint 19

[otadmin]

Have a problem with furniture and the furniture editor after upgrading to Linux Mint 19. Installed from Repositories SweetHome3d Version 5.7, furniture and furniture-nonfree.

Problem 1: SH3d comes only with very little furniture. Installing furniture adds a folder in usr/share/sweethome3d (not in .eteks) called "Furniture". It contains a handful of sh3f-libraries. But SH3d does not read this additional libraries - still only the original few pieces of furniture.
I have additional libraries under /home/user/.eteks/furniture which I used before but they are also not recognised.
How can I get SH3d to "see" .sh3f libraries?

Problem 2: The repositories install the Library Editor Version 1.22-1. This does not work but I downloaded manually Version 1.23.jar and this does work. Repositories need upgrading.

Removed the version from the repositories, downloaded version 6.0 and everything is working again. Lots of furniture. The packages need to be updated.

Sorry, I don't manage Ubuntu repositories. They decided some time ago to rely on Java 10 without warning me, whereas Sweet Home 3D 5.7 relied on Java 8.
This bug is now fixed in Sweet Home 3D 6.0, but Ubuntu propably didn't update its repositories yet.
