I think it is fine to "allow java 8" but not require it.
Requiring the latest version of java to run
Jenkins just means that many shops will stop
upgrading Jenkins.
Compared to whatever new esoteric language
features JDK8 has, stability of the Jenkins
production platform concerns far outweigh
convenience or curiosity concerns for Jenkins
developers.
To put it graphically:
Production platform stability: whale
Jenkins developer convenience: anchovy
So that's my vote. ;)

As much as I love the idea as a developer, this

users.
For one, we aren't just talking about optionally
taking advantages of Java8 library features,
like we do today for Java7. Here you are
proposing to compile version 52 class files that
only Java8 understands.
It is also not just so called esoteric OSes that
do not have Java8. Take Ubuntu for example. The
current latest release 14.04 still
<http://packages.ubuntu.com/search?suite=trusty-updates&searchon=names&keywords=openjdk>doesn't
have Java8 as a native package. IIUC you
currently have to rely on installing it from
somebody's private repository (and I have no way
of trusting these guys.) This means our DEB
package will not be installable on its own.
Here's another one. IBM still hasn't released
JDK8. If you are an IBM shop and need to use IBM
JDK for support contracts, you'll be left behind.
I'd be happy to be proven wrong, but I don't
think JDK8 dependency will be happening any time
soon.

Do we have stats for connected slaves? I

Since only relatively few Jenkins installs
actually seem to use slaves, that's not the case.
Out of ~27300 slaves, only ~200 are known to run
any of the platforms mentioned above.
Unfortunately, we don't know the OS of ~6500
slaves and I don't see why this should be the
case.
(Of course, one could argue that the more likely
an organization is to have lots of nodes and use
obscure commercial Unixes, the less likely it is
they participate in anonymous usage statistics
-- but that makes it their problem IMO.)
