This logic does not make sense at all.

When an exception happen, you catch it, and then you can simply
ignore it if that is really what you want to do depending on the
exception, or you print some error message and also ignore it,
or you can throw it again.  The point is, raising an exception and 
handling it, are 2 different issues. So your point about the program 
abruptly aborting do not make sense.

In Java, exceptions are used so much, that it is hard to find 10 lines
of java code without a try/catch in them somehwhere. 

And when you talk about a 'local error', I think you have you dark glasses
on. Do you know that a number being one bit off, can end up causing 
the most major problems in the system down the stream? you'll end up 
with small bad data, traveling across the program, generating more bad 
data every where as it feeds more functions, which can end up with 
much more damage across all parts of the system.
