    Description

      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.
