We're incorrectly seeing low priority warnings in Hudson when the above configuration should not be generating any. Looking at both findbugs.xml and findbugsXml.xml confirms that only normal and high priority issues are included in the findbugs output files.

Here's what we're seeing in Hudson. Apologies for the formatting, I'll also attach a screenshot. Each group is a row in the "Warnings" tab of the Details section, each line is a cell. One interesting observation is that there are two Maven modules here; the first is reporting correctly, the second is reporting everything as Low priority.
