On macOS when generating runtime installer DMG package version is only used in file name. For example `TestJDK-27.0.0.dmg`. Which makes `1.2.3-SNAPSHOT` valid version for macOS runtime installer DMG case.

I think we need follow up bug to figure out all possible combinations on how version is being used and normalized it for specific cases.
