Description

Looks like several of our branches have had some warnings introduced recently.

I'm going to go through and clean these up if possible. Mostly, they're trivial warnings about unclosed resources (or potentially unclosed resources), and unused code.

Some are only showing up in more recent Java compilers or IDEs. Others were introduced with code changes.
