So changed first line in script to
exit(0)
so that script did nothing

ran :
java -jar /Users/Jeff/Documents/SikuliX/Sikulix-Current.jar -r /Users/Jeff/Documents/Sikuli_Live/SikuliScripts/Vikings/Code/Command_File.sikuli

result :-
[info] Exit code: 0

this problem can simply be ignored. Does not do any harm.
will be fixed in 2.0.5
