Use at your own risk! Note that you most likely want to set to false the two options we
demonstrate above (JsonGenerator.Feature.AUTO_CLOSE_TARGET and JsonParser.Feature.AUTO_CLOSE_SOURCE)
as we do so your mapper will not close streams which we may need to reuse if we have to
resend a network request.setMapper
