The FindBugs Plugin 4.0 is not working in the Hudson. I install, the plugin is located at the plugins folder, I restart the Tomcat 5.5 and when the app is on again, the fields and options of the findbugs doesn't appear in any job page. When I restart the Tomcat, the plugin is still being showed at the available plugins page, and in the plugins folder too, both files, the 'hpi' file and the 'findbugs' created folder. Obs.: To workaround my need, I'm using the "Violations plugins".
