Re: [VOTE] JDK 1.7 - Switch for Accumulo 1.6.0

There is concern that has been voiced by users in which this may
alienate them from moving to Accumulo 1.6. Many arguments for moving to
Java 1.7 are based on wanting to use some new feature or syntactic
sugar. Also, not building artifacts against Java 1.7 would not keep
people from running with Java 1.7 (even though Accumulo was built
against 1.6).

On the other side, Oracle has stated that no further security-related
issues will be patched on Java 1.6. Given that most people using
Accumulo are security minded, this is important.

Forcing Java 1.7 alienates a group of users. Allowing users to run with
Java 1.6 or 1.7 virtual machines satisfies all parties. As such, I don't
believe this is best.

Like John said, I agree that adequate discussion hasn't been had here to
justify forcing a change. Accumulo is not that popular that we can force
people to do what we think is best. I would be happy to continue to
participate in discussions as to the concrete benefits forcing Java 1.7
