Description

As 1.7 becomes the default Java in more and more operating systems, and security-related bugfixes and other fixes in Java itself are targeted more towards newer versions, rather than maintaining older versions, it would be prudent to switch to using 1.7 as our target platform.

This change would allow us to leverage some of the newer features of Java.

This change can be established at the beginning of the development cycle for Accumulo 1.6.0, so that we can immediately begin taking advantage of the new Java features in 1.6.0 features after 1.5.0 is released.
