> 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
> Priority: Major
> Fix For: 1.10.0
>
>
> 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.
