Camel-Restlet 2.14.0 Content-type instead of Content-Type

With *camel-restlet 2.13.*1, my code used to look into*
org.restlet.http.headers* to identify the Content-Type, I upgraded to*
camel-restlet 2.14.0*, and my code is failing, as it wasn't able to find the
Content-Type in the org.restlet.http.headers
On comparing the headers in both versions, I see that camel-restlet 2.14.0
has *Content-type* instead of* Content-Type*.

Series<NamedValue;String>> series = (Series<NamedValue;String>>)
headerMap.get("org.restlet.http.headers");
*camel-restlet 2.13.1*
