I haven't spawned an external command from Java in a very long time, but I'm not entirely certain that the command didn't execute. You have a process start command followed by a bunch of stuff that affects stdio redirection, and I'm suspecting that the command is running and completing before you've set up the channels to receive the output, so the output is falling out into the Twilight Zone
