I have to note that we can make Mercurial clones much less painful if we adopt what Mozilla does for
their large repositories: providing the bundles that are cached on CDN for ether automatic or manual
clones [1]. What we have at my build server [2] is basically a stop-gap, and can be solved on server
side without considering switching to Git. Would be awesome if Skara explored if that is a viable
way for OpenJDK.
