Puede ampliar fácilmente GrizzlyWebContainerFactory para cumplir este requisito (dado que la clase es definitiva, he creado una utilidad independiente que le permite vincular el socket de escucha al localhost). Puede usar esta utilidad como:
SelectorThread threadSelector = GrizzlyWebContainerFactoryUtil.create("http://127.0.0.1:8080/", initParams, true);
Al establecer el último parámetro en verdadero lo obliga a vincularse a localhost. El único código añadí para apoyar este requisito es:
selectorThread.setAddress(InetAddress.getByName("localhost"));
La clase de utilidad entera se muestra a continuación:
