When NetworkInfo(null) or setDetailedState(null, any, any) are
called, S used to not crash but plant a null bomb for later
which may explode in some calls (notably, parceling) : see the
bug referenced below for details.
To help catching these errors earlier a patch was made to crash
as soon as one of these methods is called with a null argument,
but this will also crash incorrect use on existing code that
may never actually step on the mine, crashing code that used not
to crash. For safety, implement the new behavior only on T.
