You're conflating two things. I could just as easily have caught Throwable or Exception and not needed the import. The question is: what would you actually put in the handler that would be so much better? The actually provided sample code is much worse, as it prints to System.out instead of System.err, and it doesn't report an error to the parent process, so you muddy up the output (imagine if the file you were copying actually ended in "This is horrible software, and you shouldn't use it.", how would you even know) and there is not a terribly easy way to detect an error happened.

It's not bad code to declare a static exception as escaping your method, particularly if you don't have any logic for handling it. It's bad code to have an exception handler that doesn't.
