    If this cask is upgraded, previous stale versions will be left under
    'Caskroom/zulu/{version}'. Stale versions may also be left under
    '/Library/Java/JavaVirtualMachines/zulu{version}.jdk'. Removing them may
    require manual deletion, e.g.

      rm -rf /opt/homebrew-cask/Caskroom/zulu/
      rm -rf /Library/Java/JavaVirtualMachines/zulu*.jdk
