No space allowed would be simpler.

I'm thinking this option must be specified to generate module-info.java 
file and the module-info.java should be placed in the source tree.  
Otherwise, if jar --module option is invoked during their build process 
that I think would be the primary use of this option, it would either 
turn off generating module-info.java with another option or the 
generated module-info.java is ignored.

Perhaps jar -v option can print the module-info.java to stdout.
