JaVis: A UML-Based Visualization and Debugging Environment for Concurrent Java Programs

Debugging concurrent Java programs is a difficult task because of multiple control flows and inherent nondeterminism. It requires techniques not provided by traditional debuggers such as tracing, visualization, and automated error analysis. Therefore, we have developed the JaVis environment for visualizing and debugging concurrent Java programs. The information about a running program is collected by tracing. The Unified Modeling Language (UML) is used for the visualization of traces. Traces are automatically analyzed for deadlocks. The tracing is implemented using the Java Debug Interface (JDI) of the Java Platform Debugger Architecture. The visualization is integrated into the UML CASE tool Together.
