Yeah, since we're upgrading, it may as well be to Java 8 since it (seems
to be) be available for every OS we package for, and it would minimise
the pain for users, rather than splitting it across two updates.
I don't think we specify the required Java version in most of our native
package specs, and WAR users upgrading will have no way of knowing about
the Java requirement change, so we probably need to do a lot of user
education in advance.
Maybe we can have banners inside the web interface for one or two
releases in advance, warning about the impending Java version
requirement? Plus big red text in the changelog, articles on the blog,
Twitter etc.
Some banners on the website, wiki and issue tracker (as we sometimes do,
e.g. for donation or JUC advertising) would also be a good idea.

I'm absolutely +1 on the advantages on the programming model that
defining a JDK8 as a minimum JDK would give us. And like Nicolas, I also
think JDK7 is not really worth it as 8 is.
And Jenkins is one of those tools that has somehow a lower barrier on
that requirement upgrade, since for example the build JDK can a totally
different one, or wouldn't impact say a ruby/C/whatever compiler anyway.
Btw, I guess we own at least of those AIX installs, and JDK are actually
generally not so that behind. JDK8 for AIX seems to be not GA *yet* but
I'm sure IBM is working on it if not already out (found
http://www.ibm.com/developerworks/java/jdk/beta/ for example).
Sure, old platform like AIX 4 or 5.x wouldn't have those JDK supported,
so I suppose there could be some Jenkins VeryLTS to keep Java 6 as it's
now for say some months or even a year for only very important issues.
That would give time for those platform a bit more time to provide the
JDK8 port/version for their OS.

I checked the anonymous usage stats a few weeks ago:
Out of 93,400 installs, we know the master's OS for 85,200 of them.
285 are AIX. 120 are HP-UX. 50 installs total on OpenBSD, Darwin,
OS/400, z/OS and NetBSD.
Not relevant enough IMO if the advantages are significant.
I can provide the queries I used if anyone wants to verify these.
