After reading through about half of those examples, I can't go on.
The only one I saw that was potentially useful was the multi-catch. Half of the rest were things I had never even seen, and couldn't imagine letting slip by a code review (who uses control flow without brackets?), and the other half were so trivial that I wouldn't even waste the time to run the tool for them (why is the non-null case even preferable to do first? most people I know prefer the input validation step first anyway).
