Static Analysis of Java Programs

The project SHADOWS has started research which is developing software for automatic bug healing. We work with self-healing software, which looks for concurrent bugs. If the~detection software finds a bug, the healing action will be performed. After every healing action, one would like to know whether this action has fixed the detected problem and, perhaps even more importantly, that it has not caused any other, possibly even more serious, problem. Therefore this paper describes a technique which gives the answer for this question after automatical healing. One can fix some concurent bugs by adding healing locks. One does healing assurance by searching monitorenter instruction and uses Control Flow Graph analysis over Java byte-code. The prototype uses static analysis (tool FindBugs) for this purpose
