-----------------------------------------
Summary: Double release of netty buffer
Key: CAMEL-11151
URL: https://issues.apache.org/jira/browse/CAMEL-11151
Project: Camel
Issue Type: Bug
Components: camel-netty4-http
Affects Versions: 2.18.3
Reporter: Valentin Tsvetkov
I try to make simple proxy application with netty4-http component to transfer
http request with large content.
Example
from(String.format("netty4-http:http://0.0.0.0:%d?httpMethodRestrict=GET,HEAD,POST,PUT,DELETE,TRACE,OPTIONS,CONNECT,PATCH&chunkedMaxContentLength=100000000&disableStreamCache=true";,
8081))
.id("nettyInputRoute")
.process(new Processor() {
.toD("netty4-http:http://somehost:8080/?bridgeEndpoint=true&throwExceptionOnFailure=false&useRelativePath=true";).end();
So if i use &disableStreamCache=true option then i get
[Camel Thread #3 - NettyClientTCPWorker] WARN
io.netty.util.concurrent.DefaultPromise - An exception was thrown by
org.apache.camel.component.netty4.NettyProducer$ChannelConnectedListener.operationComplete()
io.netty.util.IllegalReferenceCountException: refCnt: 0, decrement: 1

io.netty.handler.codec.http.DefaultFullHttpRequest.release(DefaultFullHttpRequest.java:102)
at io.netty.util.ReferenceCountUtil.release(ReferenceCountUtil.java:84)
If i does not use &disableStreamCache=true, all works fine. But for large
content i get heap space error.
There are several resolved bugs in camel and netty4 that seems to be related
