             Summary: CSVPrinter ill-suited in multithreaded environment
                 Key: CSV-143
                 URL: https://issues.apache.org/jira/browse/CSV-143
             Project: Commons CSV
          Issue Type: Improvement
    Affects Versions: 1.0
            Reporter: Andras Sereny


CSVPrinter doesn't support multiple threads writing to the same appendable. The class itself is not thread safe and, what's worse, it also invalidates any thread-safety guarantees provided by the underlying appendable, as in one CSVPrinter.print method there are multiple calls to out.append.

OpenCSV does better here: in CSVWriter.writeNext there is one single call to PrintWriter.writer, thus it conveniently propagates PrintWriter thread-safety.
