JP Moresmau commented on CAMEL-11028:
-------------------------------------

I get the same issue in 3.14. Using rest with a JSON RESTBindingMode causes a duplicate content-type to be set.

> This is essentially the same as https://issues.apache.org/jira/browse/CAMEL-9613 . When I send a request containing a 'content-type' header it will get sent with duplicate values. E.g. Content-Type: \[application/json, application/json\].
> My RouteBuilder is very simple at the moment:
> {code}
> restConfiguration().component("spark-rest").port(8585);
> rest("/").post("/charges").to("direct:charges");
> from("direct:charges").to("http://localhost:8080/charges?bridgeEndpoint=true&throwExceptionOnFailure=false");
> {code}
> Having looked at the code I can see it being added in two places:
> https://github.com/apache/camel/blob/master/components/camel-spark-rest/src/main/java/org/apache/camel/component/sparkrest/DefaultSparkBinding.java#L73
> https://github.com/apache/camel/blob/master/components/camel-spark-rest/src/main/java/org/apache/camel/component/sparkrest/DefaultSparkBinding.java#L109
> Is this intended behaviour? If so, how would I disable it? Thanks
