So, in preparation for trying this I'd installed Java 8, as the install instructions told me to.
But I noticed that in the log, it said I'm running Java 13.
So I went to my programs and features app in control panel, and saw I had 2 versions of java installed simultaneously.
I'm guessing the older V13 installation was taking priority away from V8, and that's why it wasn't working. Because as soon as I uninstalled the V13 version, I retried Ubooquity.Jar and it booted right up, utilizing Java V8 now, I assume.
Hey!
