> Seems jsefa 1.1.1 is on central, task is to:
> - check license is still compatible with apache
> - upgrade our version in our extension
> - add header support for csv (and maybe more)
> if it can help on the last point I used in a project:
> {code}
> public class JSefaWriterWithHead extends JSefaCsvWriter {
>     @Inject
>     @BatchProperty
>     private String header;
>     @Inject
>     @BatchProperty
>     private String headerLineBreak;
>     @Override
>     public void open(final Serializable checkpoint) throws Exception {
>         super.open(checkpoint);
>         if (isEmptyFile(checkpoint)) {
>             transactionalWriter.write(header + ofNullable(headerLineBreak).orElse(System.getProperty("line.separator")));
>         }
>     }
>     private boolean isEmptyFile(final Serializable checkpoint) {
>         return checkpoint == null || Number.class.isInstance(checkpoint) && Number.class.cast(checkpoint).longValue()
== 0;
>     }
> }
> {code}
