RESTEasy - add a resource class dynamically

Question

With RESTEasy I\'ve implemented a subclass of Application to provide a list of singleton resources. Is there a way to add another singleton dynamically later on? I\'ve not found

I use Reateasy with Undertow in embedded environment, where I manually instantiate ResteasyDeployment, and register Resource class is really easy, see code snippet blow:

    UndertowJaxrsServer undertowJaxrsServer = new UndertowJaxrsServer();
    ResteasyDeployment resteasyDeployment = new ResteasyDeployment();

    undertowJaxrsServer.start();
    resteasyDeployment.start();

    final DeploymentInfo undertowDeployment =
        undertowJaxrsServer
            .undertowDeployment(resteasyDeployment)
            .setContextPath("/abc")
            .setDeploymentName("TEST")
            .setClassLoader(Thread.currentThread().getContextClassLoader());

    undertowJaxrsServer.deploy(undertowDeployment);

    resteasyDeployment.getRegistry().addSingletonResource(new ResourceApiImpl());
