In scenario 1, the installer would be Bar-1.0.{exe, msi, pkg ...}
The change in test above tests this.
Scenario 2 would be an error currently, since all jpackage commands require a "--name" argument, however, it would be reasonable to modify restriction to require either a name or an app-image, extracting the name from the app-image in this case.
