Yes, I feared this might be a concern. If we change how `jpackage` defines `ALL-DEFAULT` we could reduce it. The remaining use would be the case for issuing a warning for missing `jmods` directory, for which it's probably not worth keeping the dependency. Input from `jpackage` devs would be appreciated. ------------- PR Review Comment: https://git.openjdk.org/jdk/pull/22644#discussion_r1875986081
