             Summary: Enrich with REST+netty hangs when connection is closed without response
                 Key: CAMEL-16178
                 URL: https://issues.apache.org/jira/browse/CAMEL-16178
             Project: Camel
          Issue Type: Bug
    Affects Versions: 3.7.2, 3.4.5
            Reporter: Krzysztof Jamróz
         Attachments: EnrichWithoutRestResponseTest.java

Enricher hangs when used with REST endpoint utilizing netty when there is no response from the server but the server immediately closes the connection. In such case read timeout is ignored as connection is already closed.
 
The reason of this behavior is that {{org.apache.camel.component.netty.handlers.ClientChannelHandler.channelInactive}} contains following conditions for callback invocation when there was no response: 

{code:java}
configuration.isSync() && !doneUoW && !messageReceived && !exceptionHandled
{code}

where

{code:java}
doneUoW = exchange.getUnitOfWork() == null
{code}

It works as expected when initially there had been UoW in Exchange (this is the case when using {{to}}). However, enricher by default (and by design) clears UoW for exchange it creates and this breaks above check.

Setting {{shareUnitOfWork}} for {{enrich}} works around the problem.
