client startup error: UnsatisfiedLinkError: no glassgtk3 in java.library.path: .

I've just installed faf-linux via the readme, but it refuses to run.

When I call ./run it briefly displays the faf client splash screen, but then errors out in a regular java swing kind of like panel with the following information:

An error has occurred during startup:

This is shown in the terminal where I started the run script:

Context:

I'm running OpenSUSE Tumbleweed and have the Temurin 21 JDK installed.

EDIT: I don't know if it's important, but I don't see libglass.so in /usr/lib64/jvm/temurin-21-jdk/lib/

FIXED

1. I downloaded the OpenJFX SDK (same version as the OpenJDK obviously) and copied all of its lib*.so files into the local Temurin OpenJDK/lib folder)
2. I installed the packages for libgthread (both 32bit + 64bit) because it was missing on the default OpenSUSE Tumbleweed installation: sudo zypper in libgthread*
