Description

Findbugs hasn't gotten a decent update in a few years. The community has since forked it and created https://github.com/spotbugs/spotbugs . Running the RC1 on trunk has pointed out some definite problem areas. I think it would be to our benefit to switch trunk over sooner rather than later, even though it's still in RC status.
