> I am using camel-netty4-http 2.15.1 version and getting the following NPE in
> org.apache.camel.component.netty4.http.NettyHttpProducer$NettyHttpProducerCallback.done.
> Debugging through the code it seems like null check for response is missing.
> public void done(boolean doneSync) {
> try {
> NettyHttpMessage nettyMessage = exchange.hasOut() ?
> exchange.getOut(NettyHttpMessage.class) :
> exchange.getIn(NettyHttpMessage.class);
> if (nettyMessage != null) {
> FullHttpResponse response =
> nettyMessage.getHttpResponse();
> // Need to retain the ByteBuffer for producer to consumer
> // TODO Remove this part of ByteBuffer right away
> response.content().retain(); <-- response in null
> if (response != null) {
> java.lang.NullPointerException
