Visualization of exception propagation for Java using static analysis

We first present a static analysis based on a set-based framework, which estimates exception propagation paths of Java programs. We construct an exception propagation graph from the static analysis information, which includes the origin of exceptions, handler of exceptions, and propagation paths of exceptions. We have implemented the exception propagation analysis and a visualization tool which visualizes propagation paths of exceptions using the exception propagation graph. This propagation information can guide programmers to detect uncaught exceptions, handle exceptions more specifically, and put exception handlers at appropriate places by tracing exception propagation.
