Wildcard * not matching headers element in RequestMapping annotation

Question

I need to pass a token variable through an HTTP Header, so that I can process it within the method it calls. I am using a wildcard 1 for this:

@RequestMapping(value = "/{id}", method = RequestMethod.DELETE, headers = {"Accept=application/json","Token=*"})
public ResponseEntity<String> deleteFromJson(@PathVariable("id") Integer id , @RequestHeader("Token") String token) {
}

It happens that whenever I send any header like "Token: 123", it is ignored by the application and does not enter the method. It only enters it when I send the header "Token: *" just exactly as defined, thus ignoring the wildcard.

Any ideas on what can go wrong? Thanks.

As the javadoc states

Also supports media type wildcards (*), for headers such as Accept and Content-Type.

You can't use it for others.
