Made the working directory of the current process, and when we want to change the working directory when the process can also set the current working directory, but, in fact, user.dir the system environment is not reset, a lot of problems, the most common problem, all the threads under the current process in use environment variable, if you modify it, danger can be imagined, Suns JDK This estimate is a small BUG.
