Jersey application can't scan JAX-RS resources when deploying it to EAP 6

Issue

• Have configured Jersey to scan JAX-RS resources in a specific package by adding the following init parameter to Jersey Servlet declaration in web.xml:

<servlet>
    <servlet-name>JerseyWebApplication</servlet-name>
    <servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class>
    <init-param>
        <param-name>com.sun.jersey.config.property.packages</param-name>
        <param-value>com.example.resources</param-value>
    </init-param>
</servlet>  

When I deploy it to EAP 6 I have the following error:

JBWEB000289: Servlet ServletAdaptor threw load() exception: com.sun.jersey.core.spi.scanning.ScannerException: The URI scheme vfs of the URI vfs:/your/resource/class/url is not supported. Package scanning deployment is not supported for such URIs.
Try using a different deployment mechanism such as explicitly declaring root resource and provider classes using an extension of javax.ws.rs.core.Application

• Using packages to scan the resources classes are not having any effect. Resources aren't getting registered. My Application class looks like the following:

@ApplicationPath("resources")
public class MyApplication extends ResourceConfig {
    public MyApplication() {
        packages("com.example.rest;org.bar.rest");
    }
}

If I register the resource manually using the register method it works.
