There is an eternal debate about how much trust to put into these APIs. We
have the analogous issue on input where we e.g. call
someCollection.toArray() and depend on the collection not to retain a
pointer to the array. We do not in general try to protect all of our
objects against such abuse, with the exception of String, for which
guarantee iron immutability (not counting reflection or Unsafe).
Otherwise, we'd have to do the usual do-we-trust-them dance with:
if no security manager or caller class is trusted boot class then do the
