Automatic Detection of Shared Objects in Multithreaded Java Programs

This paper presents a simple and efficient automated tool called DoSSO that detects shared objects in multithreaded Java programs. Our main goal is to help programmers see all potentially shared objects that may cause some complications at runtime. This way programmers can implement a concurrent software without considering synchronization issues and then use appropriate locking mechanism based on the DoSSO results. To illustrate the effectiveness of our tool, we have performed an experiment on a multithreaded system with graphical user interfaces and remote method invocations and achieved promising results.
