Ideally, this should go to the hotspot team forest. That forest doesn't 
require integration approval. If you've the fix committed as part of 
this push, I've no strong objections to jdk8u-dev as long as all jdk and 
hotspot JPRT tests are green. It requires a noreg label

Like 8068915 - ideally it should go to the 8u hs-dev team forest first.

Needs a noreg label.

Consider these approved but please seek guidance from Alejandro on 
whether some of the hotspot specific fixes should enter 8u codeline via 
the 8u hotspot team forest.

Sean.
