For a concurrent program, a prediction tool maps the history of a single run to a prediction of bugs in an exponential number of other runs. If all those bugs can occur, then the tool is sound. This is the case for some data-race tools like RVPredict, but was, until now, not the case for deadlock tools. We present the first sound tool for predicting deadlocks in Java. Unlike previous work, we use request events and a novel form of executability constraints that enable sound and effective deadlock prediction. We model prediction as a general decision problem, which we show is decidable and can be instantiated to both deadlocks and data races. Our proof of decidability maps the decision problem to an equivalent constraint problem that we solve using an SMT-solver. Our experiments show that our tool finds real deadlocks effectively. We also show that our model is expressive by using our tool to predict more, real data races than RVPredict.
