grails-core: Controller beforeInterceptor is not called in grails 3.0.1

When making a trivial beforeInterceptor in a controller, the interceptor is not called.

Example controller in simple helloworld app:

package helloworld3

class HelloController {

def beforeInterceptor = {
    println "*** beforeInterceptor ***"
}

def index() { 
    render "Hello world!!"
}

}

When running the app with gradle bootRun and going to the http://localhost:8080/hello/index , the browser shows “Hello world!!” as expected but the debug string from the beforeInterceptor is not writen in the terminal running the “gradle bootRun” command.

An analog grails 2.5.0 app runs as expected and prints out from the beforeInterceptor.
