This is done by checking if the class "jline.console.ConsoleReader" is found - we assume that if ConsoleReader is found, everything of jline is there. So some parts of jline (and maybe a older/newer version than what we support) must be on your classpath.

Turns out, I indeed had an old version of jline, which was hiding in some jar.
Didn’t remember that, and there was no source dependency to be found.
Removing it from the jar and SOMns-native builds successfully :)

Thank you
Stefan
