> I am not entirely sure if this is a bug yet, but we should investigate. It seems that in some cases, the stream caching advice causes messages to created. 
> Flow: 
> 1. https://github.com/apache/camel/blob/camel-4.1.0/core/camel-base-engine/src/main/java/org/apache/camel/impl/engine/CamelInternalProcessor.java#L995-L998 
> 2. https://github.com/apache/camel/blob/camel-4.1.0/core/camel-support/src/main/java/org/apache/camel/support/AbstractExchange.java#L496-L498
> 3. And either one of 
> 3.1 https://github.com/apache/camel/blob/camel-4.1.0/core/camel-support/src/main/java/org/apache/camel/support/AbstractExchange.java#L413-L419
> 3. 2 or https://github.com/apache/camel/blob/camel-4.1.0/core/camel-support/src/main/java/org/apache/camel/support/AbstractExchange.java#L453-L461
> If there's no message, maybe it would be better to not create it just for reset. We should investigate this.
