Scott is right, see also the table in java.nio.file.Files where this is 
more clearly explained:

CREATE_NEW
If this option is present then a new file is created, failing if the 
file already exists or is a symbolic link. When creating a file the 
check for the existence of the file and the creation of the file if it 
does not exist is atomic with respect to other file system operations.

CREATE
If this option is present then an existing file is opened if it exists, 
otherwise a new file is created. This option is ignored if the 
|CREATE_NEW| option is also present or the file is opened only for reading.
