That is not the issue we have though,  but instead the issue we have is if
the application ONLY has y.jar (this fails module resolution at runtime on
startup).

If y.jar contains 2 modules but there is no x module in the module-path ...
how does the second x.y module in y.jar work / how does it change the
module resolution so that it does not produce the same error?
