Comment 2 for bug 1773532

I already opened a task in the German forum...

https://forum.ubuntuusers.de/topic/falsche-java-version-ausgefuehrt/#post-8973682

what I tried since:

changing the file /usr/share/sweethome3d/sweethome3d.sh so it would run with Java8 by entering some things like [find_java_runtime openjdk8] at places where I thought it might be helpful...

further notifiable is:
when Typing [sudo update-alternatives --config java], it shows me that Java8 is already standard. No Idea why it still opens with Java11 after not finding Java7
