Description

http://n2.nabble.com/DISCUSS-Drop-build-support-for-Java-5-td2539470.html#a2540533

We've had the discussion about dropping Java 5 support (build and runtime) from trunk. The above referenced string of notes indicates a favorable response. Before we do an official 2.0.0 release, we should make this change.

Besides the build aspects, I believe we still have some Java 5 runtime implications in our runtime as well – some reflection processing due to the jdbc4 support. We should clean that up as well.

I've talked to Donald about this and he's game to start this process, but please contribute ideas and testing as you see fit. Thanks.
