> The sticky bit has no effect specified at create and mkdirs. 
> The sticky bit is dropped when umask is applied. {{applyUMask}} method does not take over the sticky bit from the original {{FsPermission}} class.
> In contrast, the sticky bit specified in POSIX' create or mkdir system call is always reflected.
