Benedikt Ritter commented on CSV-96:
------------------------------------
How about checking this in CSVParser? We could initialize a lexer, get the
first record, check this record against the header and reset the Reader
afterwards (this has to happen in CSVParser ctor). This way we would do the
test only once (and not for every record). There will be only minimal impact on
performance.

> CSVRecord does not verify that the size of the header mapping matches the
> number of values. The following test will produce a ArrayOutOfBoundsException:
> {code}
> @Test
> public void testInvalidHeaderTooLong() throws Exception {
> final CSVParser parser = new CSVParser("a,b",
> CSVFormat.newBuilder().withHeader("A", "B", "C").build());
> final CSVRecord record = parser.iterator().next();
> record.get("C");
> }
> {code}
