Using Runtime.exec to fork another instance of the current process

Question

I'm trying to use Runtime.exec to start a copy of the current process. I am not necessarily interested in a fork because I don't need to share state. Is there a way I can determine the command used to start the current process and just re-run this?

Answer 1

如果在Linux上，您可以执行“ ps -eax”命令并为您的pid使用grep（不确定如何获取当前的vm pid）来获取启动您的vm的完整命令？

Answer 2

我最终从System.getProperty（“ java.class.path”）中提取了类路径，从而可以重新创建命令行参数。
