do you mean that if you don't call "waitfor()" you don't get the streams?
or did i missundertand?
if this is it it's pretty stupid, you should be able to grab the streams
and anyway the waitfor() should stuck the thread until all is done
(i mean you already read the confirmation question and typed the new
password and he's not waiting for input anymore and he called the exit()
method and you closed all streams).
try to call waitfor() only when you're sure you don't need to type
anything else.
