Description

I have a problem regarding a rest route and a client sending multiple values in the Accept header. The route has the client request validation enabled.

# succeeds
$ curl -v -H "Accept: application/json" localhost:8080/api/hello
{"message":"hello world"}

# fails
$ curl -v -H "Accept: application/xml, application/json" localhost:8080/api/hello
Response status is https://http.cat/406

After a quick debug, I ended up in the RestUtil class that returns false by default. It considers the accept header like invalid then and gives the 406.
