I'm using the latest (I also tried the daily version as of Feb 7th), and basically Find Bugs doesn't show anything. Previously it did show one bug, which I fixed (I had code like (new Random()).nextLong()), which it complained about. It looked like when Find Bugs was running that it was prompting me with something, but then the window disappeared so I couldn't tell. After fixing that, the Bug Explorer, Bug Reviews, and Bug Info are all empty. If I look at the .fb file, it does seem to suggest there are bugs still. Additionally when I do a Find Bugs, it does seem to indicate there are about 10 or so.
