That is a good point. Either go with latest greatest when changing or 
try to find the minimum change. We had a similar problem in JDK 8 where 
7GA did not work on macosx. At that time we took the first working 
version. I will see if I can figure out which one it is at least.

Unclear. The new hardware we received is M7, so without a change we 
can't use that hardware for any builds, which would be sad since the 
machine is very fast. I suspect that down the line we will want to use 
this class of hardware in all types of build scenarios. IMO, we get 
adequate testing that the 8GA as boot (which is the defined bootjdk) 
works on all the other platforms.
