Declaring a method as "throws Throwable" forces the caller to handle the 
exception even if the exception/error thrown is unchecked.

E.g.

void storeMessage(Message message) throws Throwable
{
}

If that method fails in any way, even if it throw a RuntimeException or 
Error then we need to handle it, since it would be a major problem if 
the message didn't get saved.

The method could be declared to not throw Throwable and the caller would 
just have to remember to catch (Throwable) but declaring the method as 
throws Throwable prevents the possibility of the caller from forgetting 
to do so.

FWIW It's debatable if it's really of much value but cases like the 
above are where I have seen it used.
