Yoshikoder won’t start on Ubuntu

Two days ago my Yoshikoder refused to start on the Ubuntu (GNU/Linux) machine. So I tried in the console java -jar Yoshikoder-0.6.4.jar and was informed that “Error: Assistive Technology not found: org.GNOME.Accessibility.AtkWrapper”. A quick on the web look turned out that the solution is simple. In the console, I opened the following file:

sudo leafpad /etc/java-11-openjdk/accessibility.properties

and commented out the line causing problems (in my case it was the last line), so that it reads:

#assistive_technologies=org.GNOME.Accessibility.AtkWrapper

Sorted.
