Review Comment:
   > where the file is closed
   
   please do not forget to mention `flush`, as well. Its just as unnecessary to 
do so, like all the rest we see here.
   
   Having to `flush` manually is very rare, therefore its just old coding 
propagating **feature envy**, facing the `autocloseable` feature.
