That's exactly the difference. Why do you need to catch the exception?
All you're doing is destroying all the information, rendering it down
to a blunt "has failed".

We've had several threads touching on this, recently. I'm going to say
this in what might be taken as a rude way, but the emphasis is
necessary:

** Folks, *stop catching exceptions* just to print failure messages
and exit. You are shooting yourselves in the foot. **

You should catch exceptions if you can actually handle them, but if
all you're doing is printing out a fixed message and aborting, delete
that code. Less code AND a better result.
