This looks right now. As jlink only supports packaged modules on the 
file system then each module should have a location. Another way to 
handle this case is to map it to "unknown", this should do it:

         cf.modules().stream()
                 .map(ResolvedModule::reference)
                 .filter(mref -> mref.descriptor().isAutomatic())
                 .findAny()
                 .ifPresent(mref -> {
                     String loc = 
mref.location().map(URI::toString).orElse("<unknown>");
                     ..
                 });
