> camel-netty-http - Infinite loop when setting retries
> -----------------------------------------------------
>
> Key: CAMEL-17949
> URL: https://issues.apache.org/jira/browse/CAMEL-17949
> Project: Camel
> Issue Type: Bug
> Components: camel-netty-http
> Affects Versions: 3.14.2
> Reporter: Gerasimos Kalouris
> Priority: Major
> Attachments: netty-http-bug.zip
>
>
> When setting re-deliveries in case of `NettyHttpOperationFailedException` it
> seems that the exchange is submitted back to netty's executor group without
> incrementing the attempts counter, resulting to an infinite loop. This
> example works as expected when using the `camel-http` component.
