      Description

      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
