If I read this correctly you've just changed the first line of the 
javadoc to add "if the directory already exists".  That probably should 
say "file or directory" as it may be a non-directory file. I agree with 
tweaking the description for when FileAlreadyExistsException is thrown 
but if will require a similar change, for consistency reasons, to the 
other methods that are specified to throw this exception.
