Gary Gregory commented on CSV-143:
----------------------------------

Patches welcome! :-) If your changes cannot keep binary compatibility, consider a new class
or a subclass.

> 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.
