     (Eighty-seven point three percent of cited statistics are
plucked out of thin air.  ;-)

     One problem is that "fatal" is ill-defined.  Is an NPE
"fatal?"  Quite often it is, but sometimes the application
is prepared to cope with it -- For example, think of some
code throwing NPE while being managed by an IDE's debugger,
of think of a servlet throwing NPE without taking down the
entire Web container.

     Somewhere toward the other end of the spectrum, is a
NumberFormatException "benign?"  Maybe, if the application
can protest and prompt for another number.  Or maybe not,
if the string came from a configuration file and there's
nobody to respond to a prompt.

     The "seriousness" of an exception is not a function of
the exception itself, but of the code that catches (or fails
to catch) it.
