I don't think the owner of the file is set anywhere. By default, if Java
creates a file it inherits the currently-running process as the owner. We can
do that with [`setOwner`](http://stackoverflow.com/a/28829177/70465) --
[example of how to set the permissions and owner
safely](http://stackoverflow.com/a/32165319/70465).
