I'm happy it is useful at least for you.
1. I recommend to have and use ONLY ONE version, the installer one NOT THE REPOSITORY ONE.
1.1 Also I prefer to have it all somewhere in my home folder than under /usr/.... but it's your choice.
2. Starting with SH3D-6.5 the jre8 folder was replaced with runtime.
So, copy the runtime folder and rename it as jre8 OR modify the path accordingly.
In my case I've downloaded the latest jre8 version for linux (jre1.8.0_351) and it appear to work.
