jdk8 build times

Fri Aug 30 07:08:42 UTC 2013

Two more questions:

Are you building 32 or 64bit and how many jvm variants? I built 64bit so 
only server.

What boot jdk are you using? 32 or 64bit? You haven't accidentally put a 
debug build there or something? I'm using a 64bit jdk7u something, 
probably 4 or 7, can't access the machine to check exactly today.
