Project Proposal: JDK 7 Update

Not talking about hotspot specifically, but more generally, SFAIK all 
relevant security
fixes have been backported to 6-open.
And 6-open in fact has a lot of fixes that are *not* in the commercial 
Some of those are its origins as a very early 7. Some are from backports 
were OKed for 6-open but really not considered that critical for JDK6.
But I'm very sure 6 updates have (non-security) fixes not in 6-open too.
So its all very messt.

Now something of a digression ..
I think a lot of that was down to the unexpectedly long cycle for JDK 7
and the unrelated forests for 6-open and 6 updates (as noted above)
But release managers carefully scrutinise requested backports from JDK8 
to a 7 update
because updates have less time to bake.
So in the 7 update cycle if everything is based off the same forests we 
expect that management of the content of these will need to be merged too.
