When jpackage derives bundle properties from the input data, it should get the valid values. If it can't do it, it should fail.

No idea. How is it relevant? If jpackage can't get a valid platform-specific bundle version from the module version, it should fail.

It is the opposite: applying the same normalization function to any input is simple. If it can't produce a valid output, stop further processing if there are no other options.

Besides a command line, jpackage can derive the app version from the main jar, module, and now from the runtime. 

Do you suggest handling these cases differently?
