There is no point requiring 1.7 for the sake of it.
That will exclude users who cannot upgrade from 1.6
However, if there are new features in 1.7 that make a significant
difference to the HC code, then it is worth considering.
I have yet to see any discussion of the new features in 1.7 which are
a "must-have" as far as HC is concerned.

That is not directly relevant.
Commercial entities tend to be very cautious about upgrading software,
and anyway can pay for extended support.

Well, by the time 5.0 comes out, the odds are that Java 7 will be EOL
(April 2015)! ;-)

However, there are other ways to achieve resource cleanup which don't
require 1.7
Findbugs and IDEs are quite good at reporting where resources have not
been closed.
So I would not regard that as a reason to require 1.7

I do like programming with try-with-resources, feels safer, warm and fuzzy.

I agree. ConcurrentLinkedDeque [1] may be required for lock-less
(concurrent) connection pools [2]. There might still be ways to use
ConcurrentLinkedQueue instead.
