The design and implementation of a variable history tracker system

During the process of debugging some large sized Java programs, history records of certain variable field are really necessary. But most of Java IDEs do not provide this function. In order to support the debugging of large-scale programs that run for a long time,it is necessary to introduce checkpoint techniques into debuggers for parallel programs. This paper puts forward a new tool to solve this problem. It is designed with AOP framework. At the same time, it supports distributed application. In practical application, it is proved to be useful.
