If `--add-modules ALL-MODULE-PATH` is given, jlink will find all observable modules from `--module-path` and use them as the root modules. If the root set is empty, error; otherwise, it will link with the application modules on the module path and its transitive dependences. ------------- PR Comment: https://git.openjdk.org/jdk/pull/22494#issuecomment-2515384768
