Exceptions are intended for errors that you weren't really 
expecting (running out of memory, corrupted program state, etc), 
and as such they're much more likely to occur "in the field".  To 
be able to attach a debugger to it and get a stack trace you need 
to reproduce the problem case locally, which isn't always 
possible, especially when you're not entirely sure what it is.

(This is less likely to be a problem with ANTLR-generated 
exceptions, since they should be easily reproducible just by using 
the same input file.  I'm just saying that in general the above is 
true.)
