Can you please just check if you have jre/jdk installed on ?

This error indicate that java is not available, or maybe need to be added to PATH?

During install java is needed to run testdot in Plantuml to check the ghraphviz installation. Maybe a pure js version of testdot could be implemented instead. However, without java the package wouldn't be usable anyway.
