Homayoun Zariv created CAMEL-8694:
-------------------------------------
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) {
java.lang.NullPointerException
