------------------------------------
Fix Version/s: 2.16.1
2.17.0
> RabbitMQ specific message properties are forwarded as message headers
> ---------------------------------------------------------------------
>
> 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.
