Which version of java are you using? (e.g. java -version)
and obviously all robots listed there can run, so it has to be something with your configuration.
I am using 11.0.5
I'll be removing the robot from the rumble.
Please try with Java 8. Java 9 and successive versions like java 11 has incompatible changes which may be the root cause of ClassNoDefFound error
We recently moved to java 11, but it’s never tested for old robots.
Btw, are you using OpenJDK or orcale jdk?
