SDK and JRE bundles

[Henri Gomez]

> A DMG is nice because you can put an alias to the JavaVirtualMachines folder in it like Oracle did with their Developer Preview release.  Makes installation easier and very Mac-like.

DMG is fine for JDK (ie: runtime environment) but for a Bundled JRE,
ie something to be embedded in other apps, plain tarball/zip may be
easier to use by packagers.
That's why I asked about delivery format :)
