     (I guess there's a `write' missing before the parameters.)

     Looks like the file auto-closes at the end of the operation.  From
the JavaDoc for the three-parameter write():

	This method works as if invoking it were equivalent to
	evaluating the expression:

	Files.write(path, lines, StandardCharsets.UTF_8, options);

... and the JavaDoc for the latter says

	[...] The method ensures that the file is closed when all lines
	have been written (or an I/O error or other runtime exception
	is thrown). [...]

     So it appears you're only in trouble if you want the stream
to remain open.
