文摘

Concurrent programming poses a unique set of problems for quality assurance. These difficulties include the complexities of deadlock, livelock and divergence, which can be extremely difficult to detect and debug. A variety of tools have been developed to assist designers and developers of concurrent applications. Some of these tools, such as VeriSoft, are specific to particular implementation languages, such as C++.

The Java Remote Method Invocation (Java RMI) package facilitates the implementation of concurrent applications, including those where processes reside on different hosts and communicate over networks. Unfortunately, it does not relieve the developer from the potential pitfalls of controlling concurrent access to remote objects, and may, in fact, make concurrency problems even more difficult to find.

This paper presents an approach that allows the VeriSoft state exploration system to be used to analyze Java RMI programs for deadlock, livelock, divergence, and assertion violations. The system works by transforming Java RMI programs into C++ programs where Java syntax, structure, concurrency and memory management are replaced by C++ equivalents and Java RMI communication has been transformed to VeriSoft C++ inter-process communication. We present the details of this transformation and discuss preliminary results for a number of small examples.
