-------------------------------------

             Summary: java.lang.NullPointerException in at org.apache.camel.component.netty4.http.NettyHttpProducer$NettyHttpProducerCallback.done
                 Key: CAMEL-8694
                 URL: https://issues.apache.org/jira/browse/CAMEL-8694
             Project: Camel
          Issue Type: Bug
          Components: camel-netty4-http
    Affects Versions: 2.15.1
            Reporter: Homayoun Zariv


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) {
