GWTP Rest dispatch: replace DefaultRequestBuilderFactory with own implementation

Question

My GWT frontend is on port 8888. REST backend is on 8080. By default cookies not work. Seems that cookies should be passed if I will call RequestBuilder.setIncludeCredentials() for the request. In this case I need to replace DefaultRequestBuilderFactory with my own implementation because I need to send cookies to server.

SecuredRequestBuilderFactory.java:

public class SecuredRequestBuilderFactory extends DefaultRequestBuilderFactory {
    public SecuredRequestBuilderFactory(HttpRequestBuilderFactory httpRequestBuilderFactory, BodyFactory bodyFactory, HeaderFactory headerFactory, UriFactory uriFactory, @RequestTimeout Integer requestTimeoutMs) {
        super(httpRequestBuilderFactory, bodyFactory, headerFactory, uriFactory, requestTimeoutMs);
    }

    @Override
    public <A extends RestAction<?>> RequestBuilder build(A action, String securityToken) throws ActionException {
        RequestBuilder builder = super.build(action, securityToken);
        builder.setIncludeCredentials(true);
        return builder;
    }
}

I have added to my gwt.xml:

<replace-with class="com.example.rest.SecuredRequestBuilderFactory">
    <any>
        <when-type-is class="com.gwtplatform.dispatch.rest.client.core.RequestBuilderFactory"/>
        <when-type-is class="com.gwtplatform.dispatch.rest.client.core.DefaultRequestBuilderFactory"/>
    </any>
</replace-with>

I have discovered from debugger (Chrome with IDEA plugin) that there is no mapping for class SecuredRequestBuilderFactory and credentials was not included.

So, any ideas how to make it work?

I found solution to pass all cookies with REST request:

SecuredRequestBuilderFactory.java:

public class SecuredRequestBuilderFactory extends DefaultRequestBuilderFactory {

    @Inject
    public SecuredRequestBuilderFactory(HttpRequestBuilderFactory httpRequestBuilderFactory, BodyFactory bodyFactory, HeaderFactory headerFactory, UriFactory uriFactory, @RequestTimeout Integer requestTimeoutMs) {
        super(httpRequestBuilderFactory, bodyFactory, headerFactory, uriFactory, requestTimeoutMs);
    }

    @Override
    public <A extends RestAction<?>> RequestBuilder build(A action, String securityToken) throws ActionException {
        RequestBuilder builder = super.build(action, securityToken);
        builder.setIncludeCredentials(true);
        return builder;
    }
}

MyRestDispatchModule.java:

public class MyRestDispatchModule extends AbstractGinModule {

    static class MyCoreModuleBuilder extends CoreModuleBuilder {
        MyCoreModuleBuilder(BaseRestDispatchModuleBuilder<?> baseBuilder) {
            super(baseBuilder);
            requestBuilderFactory(SecuredRequestBuilderFactory.class);
        }
    }

    static class MyBuilder extends RestDispatchAsyncModule.Builder {
        @Override
        public CoreModuleBuilder core() {
            return new MyCoreModuleBuilder(this);
        }
    }

    @Override
    protected void configure() {
        install(new MyBuilder().build());
    }
}
