Re: [VOTE] JDK 1.7 - Switch for Accumulo 1.6.0
I think building the binary release using 1.7, but still maintaining 1.6
compatibility is a nice compromise. You're providing enough of a carrot to
use 1.7 (hey look, we already built it for you), but you're not alienating
the users that still need 1.6 classes for whatever reason. If something
like this were to be implemented, then it would be necessary to provide
very clear documentation on how to run Accumulo on different JREs.
