See this question : How to send SIGINT signal from Java to an external process?

Can you send `kill -SIGINT <pid>` to the process (given that you know the process ID):

    Runtime.getRuntime().exec("kill -SIGINT 12345");

Of course, that would make for a platform-dependent solution... Potentially, you'll be able to use this tool, although it is in "sandbox mode". But it might give you an idea:
