Camel throws an TypeConversionException when receiving a HTTP response, where the Content-Type header includes extended information, e.g. version info.
org.apache.http.headers - [CID=879adbb4-d406-40e7-8529-5a20427157bf] - http-outgoing-0 << HTTP/1.1 400 Bad Request
org.apache.http.headers - [CID=879adbb4-d406-40e7-8529-5a20427157bf] - http-outgoing-0 << Content-Type: application/json; charset=utf-8; v=1.0
org.apache.camel.TypeConversionException: Error during type conversion from type: java.lang.String to the required type: java.lang.String with value [Body is instance of java.io.InputStream] due utf-8; v=1.0
Caused by: java.io.UnsupportedEncodingException: utf-8; v=1.0
The exception throw is TypeConversionException and the response to the caller of route will get a 404 error back, even though the original response code was 400.
It appears that Camel doesn't handle the ; v=1.0 part of the content-type header.
