Is Grails missing support for http OPTIONS requests?

Question

When I create the grails 2.2.4 app below, I see responses to POST /options/somewhere but not to OPTIONS /options/somewhere.

Is there some way to invoke a controller action on OPTIONS requests?

---

App where POST works and OPTIONS doesn't:

$ grails create-app options
$ grails create-controller api

UrlMappings.groovy:

class UrlMappings {
  static mappings = {
    "/somewhere" (controller: "api", parseRequest: true) {
      action = [OPTIONS: "getOptions", POST: "saveStuff"]
    } 
  } 
}

ApiController.groovy:

package options

class ApiController {
    def getOptions() {
      render("Your options await.")
    }
    def saveStuff() {
      render("Stuff saved.")
    }
}

Try this code:

 "/somewhere" (controller: "api", parseRequest: true) { //controller name begins with a lowercase letter
        action = [OPTIONS: "getOptions", POST: "saveStuff"]
    }

I use grails 2.0.3 and it do not work as I expected. But should work for latest grails version (2.3). Pls see related bug.
