I guess from the day-to-day programmer perspective, it
doesn't really matter unless you're keeping extra
references like above, the effect is the same (?), but
then it's one of those situations where you innocently do
keep a reference one time and end up chasing the same bug
for days ;)
I think the main conclusion for everyday programming is
that, if you must register an object with its class or
another object from the constructor, that should be the very
last thing the constructor does, after anything else that
might possibly throw an exception.
Of course, if the object's class is non-final, there is
still the problem of subclass constructor bodies that run
after the end of the superclass constructor.
A better solution is to treat registration of objects as a
separate action, and limit the constructor to building the
object's own state.
