Subject Re: [VOTE] JDK 1.7 - Switch for Accumulo 1.6.0
Date Mon, 03 Jun 2013 22:10:03 GMT
Adam, the question isn't whether we should stop supporting users on
Java 1.6. The question is whether they'd be enticed by 1.6.0 features
enough to be willing to install its prerequisites. Accumulo 1.5.0 will
continue to run on 1.6 JVMs without issue, and we can continue to
support that so long as there are a significant user group unwilling
to say goodbye to Java 1.6.

As for the motivating feature. There are some nice features
(try-with-resources, exception handling syntax, diamond syntax), but
I'm not proposing this change in order to use a new "killer" feature.
What we need to decide is whether or not we will be constrained *not*
to use these features for the development cycle of Accumulo 1.6.x. If
the answer is no, don't switch, yes, be constrained, then we can
revisit the question at the beginning of the Accumulo 1.7.0
development cycle.
