Installation latest Add-on ccu-historian 1.20 ->Java needed (Stretch-Image 2.46)

Hi,

I installed the latest Stretch-Image 2.46 and wanted to install the ccu-historian add-on.

I have two issues for improvement:
1. The default install link is to the old version 0.7.
This should be the link to the latest version 1.2 within github:
https://github.com/mdzio/ccu-historian/releases/download/1.2.0/ccu-historian-1.2.0-bin.zip

2. At least Java 1.8 is needed for ccu-historian version 1.2
Are there any plans to implement the Java Runtime installation as a prerequisite for ccu-historian?
If not, what is the best way to install Java 1.8 on M2P Stretch Image?

Thanks
Holger
