I'm playing with the wonderful [FindBugs plugin](http://hudson.gotdns.com/wiki/display/HUDSON/FindBugs+Plugin) for [Hudson](http://hudson-ci.org/). Ideally, I'd like to have the build fail if FindBugs finds any problems. Is this possible?

Please, don't try and tell me that "0 warnings" is unrealistic with FindBugs. We've been using FindBugs from Ant for a while and we usually do maintain 0 warnings. We achieve this through the use of general exclude filters and specific/targeted annotations.
