Answer 1

If the exception is being thrown from the start() method, then the OS isn't able to fork/exec the process. So the problem isn't the subprocess dying, but that it's not being launched.

So are you specifying this correctly ? Are you relying on PATH settings ? Are the execute permissions correct ?

It would be useful to see the code that you use to initialise the ProcessBuilder. i.e. the invocation parameters.
