Description

When I try to upgrade commons csv from 1.6 to the latest version 1.7. The following code breaks.

public class Demo {

	@Test
	public void TestCSV(){
		try {
		InputStream testInput = new ByteArrayInputStream(",".getBytes(StandardCharsets.UTF_8));
		Reader reader = new InputStreamReader(testInput);
		char character = ",".charAt(0);
        CSVFormat format = CSVFormat.RFC4180.withDelimiter(character).withFirstRecordAsHeader().withIgnoreSurroundingSpaces();
        CSVParser parser = new CSVParser(reader, format);

		} catch (Exception e) {
			System.out.println("!!!!!!!");
			assertEquals("java.lang.IllegalArgumentException: The header contains a duplicate name: \"\" in [, ]", e.toString());
		}
	}

}

The test should pass, but it failed with error:

org.junit.ComparisonFailure: expected:<...lArgumentException: [The header contains a duplicate name: ""] in [, ]> but was:<...lArgumentException: [A header name is missing] in [, ]>
