Howto start in FreeBSD?

I managed to start another Java based program (Strange Eons) in FreeBSD, but can’t seem to do the same with Vassal. Anyone else using Vassal in FreeBSD?

-Strange Eons starts with “java -Xmx2g -javaagent:strange-eons.jar -cp strange-eons.jar strangeeons”
-Strange Eons works with openjdk11-jre

Caused by: java.lang.ClassNotFoundException: is a shell script. You don’t run it using Java.

What you need to run from your command prompt is:


It was just that simple, thanks a million!
