Consequently, security sensitive applications should take 893N/A * care when using this option. 893N/A * <p> For security reasons, this option may imply the {@link 893N/A * LinkOption#NOFOLLOW_LINKS} option. In other words, if the option is present 893N/A * when opening an existing file that is a symbolic link then it may fail 893N/A * (by throwing {@link java.io.IOException}). 893N/A * Sparse file.
