Obviously NumberFormatException can store another exception object
inside.  This code effectively converts IllegalArgumentException into
NumberFormatException, storing the original argument exception inside so
that one can examine it later if they're curious.

It depends on what NumberFormatException can  accept as an argument.  If
it accepts an Object then it's fine.
