Description

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.

    onException(NettyHttpOperationFailedException.class)
        .maximumRedeliveries(2)
        .retryAttemptedLogLevel(LoggingLevel.WARN)
        .backOffMultiplier(5)
        .maximumRedeliveryDelay(500)
        .useExponentialBackOff()
        .handled(false);
