Yes, probably.  The right answer to the problem is usually not to handle 
the exceptions within the program, but use the exceptions to report 
errors directly to the user - at least most of the time.  I think Java 
programs always run into all kinds of troubles, because they are always 
written with a "generate more complexity than the programmer can handle" 
state of mind.

But what shoud I do with something like smartdots.fs (recently added to 
Gforth)?  It's a .s variant that prints addresses in hex, and printable 
strings as s" text", and it does use exception handling for that.  
Anything where c@ doesn't fail is an address.  The same is done on 
strings: Anything shorter than 80 characters (we don't want to print too 
long strings), with every character fetchable by c@ and printable (>=bl) 
is a string.

smart.s (it really just patches Gforth's .s, so you don't need a new 
name, and it works with ~~, as well) is not supposed to report errors to 
users, it's a mere diagnostic tool - it also should never crash.  On 
Android, it is completely useless, because it can only catch the first 
SIGSEGV.  And it sigsegvs on every single number on the stack that 
actually isn't an address (which most of them are not).

Smart.s is an idea from Gerald Wodny, and it can be helpful.  You can do 
things like this:

variable foo  ok
s" foo" foo ' foo .s <4> s" foo" foo ' foo  ok
