-------------------------
Summary: Updating from 1.6 to 1.7 breaks
Key: CSV-257
URL: https://issues.apache.org/jira/browse/CSV-257
Project: Commons CSV
Issue Type: Bug
Components: Parser
Affects Versions: 1.7
Reporter: xia0c
When I try to upgrade commons csv from 1.6 to the latest version 1.7. The
following code breaks.
{code:java}
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());
}
}
}
{code}
The test should pass, but it failed with error:
{code:java}
org.junit.ComparisonFailure: expected:<...lArgumentException: [The header
contains a duplicate name: ""] in [, ]> but was:<...lArgumentException: [A
header name is missing] in [, ]>
