> ---------------------------------------------------
>
> Key: CSV-290
> URL: https://issues.apache.org/jira/browse/CSV-290
> Project: Commons CSV
> Issue Type: Bug
> Components: Parser
> Affects Versions: 1.6, 1.9.0
> Reporter: Anatoliy Artemenko
> Priority: Major
>
> {code:java}
> // code placeholder
> {code}
> CSV, produced using printer:
>
> CSVPrinter printer = new CSVPrinter(sw, CSVFormat.POSTGRESQL_CSV.withFirstRecordAsHeader());
>
> cannot be be read with same format parser:
>
> CSVParser parser = new CSVParser(new StringReader(sw.toString()), CSVFormat.POSTGRESQL_CSV.withFirstRecordAsHeader());
>
> To reproduce:
>
> {code:java}
> StringWriter sw = new StringWriter();
> CSVPrinter printer = new CSVPrinter(sw, CSVFormat.POSTGRESQL_CSV.withFirstRecordAsHeader());
> printer.printRecord("column1", "column2");
> printer.printRecord("v11", "v12");
> printer.printRecord("v21", "v22");
> printer.close();
> CSVParser parser = new CSVParser(new StringReader(sw.toString()), CSVFormat.POSTGRESQL_CSV.withFirstRecordAsHeader());
> System.out.println("headers: " + Arrays.equals(parser.getHeaderNames().toArray(), new String[] {"column1", "column2"}));
> Iterator<CSVRecord> i = parser.iterator();
> System.out.println("row: " + Arrays.equals(i.next().toList().toArray(), new String[] {"v11", "v12"}));
> System.out.println("row: " + Arrays.equals(i.next().toList().toArray(), new String[] {"v21", "v22"}));{code}
> I'd expect the above code to work, but it fails:
> {code:java}
> java.io.IOException: (startline 1) EOF reached before encapsulated token finishedjava.io.IOException: (startline 1) EOF reached before encapsulated token finished
