That is understood but a lot of us still bear scars from the 6ux - > JDK 
7 fix deficit
and the rule was made "jdk 8 first, back port to 7". So someone would have
to negotiate an exception to this.

In mercurial there isn't such a thing as a "child". They are all peers.
So what this seems to be, is more a "cleaned up" version of
the macosx-port forest, conforming to jcheck, etc. I hope we don't
lose much of the "useful" history in doing this ...

Agree it must not cause regressions on other platforms.
But I suspect its going to take a while to get to all the tests passing ..
