>                 Key: CAMEL-9101
>                 URL: https://issues.apache.org/jira/browse/CAMEL-9101
>             Project: Camel
>          Issue Type: Bug
>          Components: camel-rabbitmq
>    Affects Versions: 2.15.2
>            Reporter: Serge Smertin
>            Assignee: Andrea Cosentino
>             Fix For: 2.17.0, 2.16.1

>
> org.apache.camel.component.rabbitmq.RabbitMQProducer#buildProperties does not remove message headers from exchange after property is set, leading to message header pollution.
> so constructs like 
> {code}
> final Object contentType = exchange.getIn().getHeader(RabbitMQConstants.CONTENT_TYPE);
>         if (contentType != null) {
>             properties.contentType(contentType.toString());
>         }
> {code}
> must be rewritten as
> {code}
> final Object contentType = exchange.getIn().removeHeader(RabbitMQConstants.CONTENT_TYPE);
>         if (contentType != null) {
>             properties.contentType(contentType.toString());
>         }
> {code}
> I don't think that these are used in business logic as this is solely transport specific.
