What is can countdown latch do in case of a error?

[i30817]

So i have a master thread that has to await a serial runnable (one for
each word in a phrase) to end.
I was thinking of using a CountdownLatch instead of the wait/notify
i'm using now (and has a bug i'm trying to find),
But i don't see a way to notify the latch (and the master ofcourse) in
case of failure right?

Never mind, just realized a volatile field set before the latch is
counted down is enough
