Review Comment:
Done.
I was basing it on
https://www.oracle.com/technical-resources/articles/java/javadoc-tool.html#format
which doesn't close the tags (I assume javadocs inherited the 'tag omission'
behavior from html).

> To return a stream of `CSVRecords` in a Spliterators, I need to call
> `CSVParser.getRecords().iterator()`. I worry that the `getRecords()` will
> load the records from the parser into memory, before creating the iterator
> which can be a problem with large CSV files.
> My code:
> {code:java}
> public Stream<CSVRecord> convertFileToMaps(Path path) throws IOException {
> try (CSVParser parser = CSVParser.parse(path,
> Charset.defaultCharset(), CSVFormat.RFC4180
> .withFirstRecordAsHeader())) {
> return
> StreamSupport.stream(Spliterators.spliteratorUnknownSize(parser.iterator(),
> 0), false);
> }
> }
> {code}
> and:
> {code:java}
> public Stream<CSVRecord> convertFileToMaps(Path path) throws IOException {
> try (CSVParser parser = CSVParser.parse(path,
> Charset.defaultCharset(), CSVFormat.RFC4180
> .withFirstRecordAsHeader())) {
> return StreamSupport.stream(parser.spliterator(), false);
> }
> }
> {code}
> When I collect the results of my method, it gives me
> {code:java}
> []
> {code}
>
> If I replace `parser.iterator()` with `parser.getRecords().iterator()` then I
> get the desired results. Is the iterator not meant to be an iterator of the
> list of `CSVRecord`.
