Visual Analytics Tool for Java Virtual Machine Execution Traces
Sammanfattning: The usage of multithreaded programs is continuously increasing, which leads to various concurrency issues. The non-deterministic approach of the thread scheduler makes the analysis of such programs complex. Thread-based visualization of the concurrent events helps to analyze a concurrent program efficiently. The extension of such visual analytics jpf-visual tool for regular JVM traces will help Java programmers to better understand and analyze the runtime execution of concurrent programs. AspectJ instrumentation with its lock() and unlock() pointcut extension makes it possible to capture important runtime events information in order to generate the JVM event trace. A successful integration of the JVM trace into the jpf-visual tool is achieved through code refactoring and the use of adapter classes. In this thesis, the implementation of such an approach is shown to analyze the concurrent events using the regular JVM. Such implementation can help to provide a generic approach for the concurrency issue analysis.
