Review comment:
       Ignoring exceptions here - and documenting that we do - seems to be the 
best approach.
   
   Another alternative would be to not change this constructor's code to use 
the new methods at all. If we want to invoke the new methods then I'd suggest 
to set `modTime` and  `size` "the old way" before invoking the new methods so 
we keep the old behaviour if things go wrong in NIO land.
