It would be quite a challenge to provide some ntfs-3g oriented help with no information about how ntfs-3g has been plugged into Java and Android.

On Posix, which ntfs-3g is expected to conform to, close() cannot return EPERM (https://pubs.opengroup.org/onlinepubs/9699919799/functions/close.html), but Android and the Java environment may have their say.
