stand alone bug tracker

I have to manage about 5 or 6 small independent projects I am working on. As for any projects, mines have bugs too. So, I have asked mr.google for some lite, stand alone bug tracker system. After browsing to a couple of company sites I have found out that all available solutions are web based. I do not need this. I would like to have something very simple - Java is prefered :-) - using a direct connection to some embedded database. Is there something like this? Update: I have found one: BugCollector Pro Defect Tracking Software for Windows. As you can see from its name it has only one drawback (guess!).
