Great, thanks! Are there any examples of using an OutputStream with Undertow?

My bad, I did not read your post properly and was thinking of gzip.

I think you can still use ZipOutputStream though, it will only be
blocking if the underlying Stream is blocking, so using something like
a ByteArrayOutputStream would make the operation non blocking. If you
want to avoid buffering the whole zip in memory you could potentially
alternate between writing data to the ZipOutputStream and then taking
anything written to the ByteArrayOutputStream and flushing it to the
response channel.
