Managed bean not found when upgrading to Mojarra 2.2.8-07 or newer

Question

I use Spring Boot, JSF, PrimeFaces.

Right now, I can't update my application to new JSF 2.2.12.

Everything works properly for example with JSF 2.2.8-06 and PrimeFaces 5.2 but starting from JSF 2.2.8-07 and up to 2.2.12 version I can't reach my ManagedBean from XHTML page.

What was changed from JSF 2.2.8-07+ version and how to fix it ?

My bean:

@ManagedBean
@ViewScoped
public class HelloBean implements Serializable {

    private static final long serialVersionUID = 8569928214435846079L;

    public String getHello() {
        return "Hello from PrimeFaces and Spring Boot!";
    }

}

index.xhtml:

<f:view xmlns="http://www.w3c.org/1999/xhtml"
    xmlns:f="http://java.sun.com/jsf/core"
    xmlns:h="http://java.sun.com/jsf/html"

        <style>
        body {font-size:12px; }
</style>
    </h:head>
    <h:body>
        <h:form>
            <prime:panel header="What do you see here?" >
                <div style="height:50px">
                    This is a simple PrimeFaces 5 project running on Spring Boot 1.1.4.
                </div>
            </prime:panel>
            <prime:panel header="JSF 2.2 Bean Access">
                #{helloBean.hello}
            </prime:panel>
        </h:form>
    </h:body>
</f:view>

WebInitializer:

@Configuration
public class WebInitializer extends SpringBootServletInitializer implements ServletContextAware {

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(Application.class);
    }

    @Bean
    public DispatcherServlet dispatcherServlet() {
        DispatcherServlet dispatcherServlet = new DispatcherServlet();
        dispatcherServlet.setThrowExceptionIfNoHandlerFound(true);
        return dispatcherServlet;
    }

    @Bean
    public ServletRegistrationBean servletRegistrationBean() {
        FacesServlet servlet = new FacesServlet();
        ServletRegistrationBean servletRegistrationBean = new ServletRegistrationBean(servlet, "*.xhtml");
        servletRegistrationBean.setLoadOnStartup(1);
        return servletRegistrationBean;
    }

    @Bean
    public ServletListenerRegistrationBean<ConfigureListener> jsfConfigureListener() {
        return new ServletListenerRegistrationBean<ConfigureListener>(new ConfigureListener());
    }

    @Override
    public void setServletContext(ServletContext servletContext) {
        servletContext.setInitParameter("com.sun.faces.forceLoadConfiguration", Boolean.TRUE.toString());
    }
}

With JSF 2.2.8-06 everything works properly except following errors in the console:

UPDATED

I got it working:

I have added resources/META-INF/faces-config.xml file:

<?xml version="1.0" encoding="UTF-8"?>
<faces-config xmlns="http://xmlns.jcp.org/xml/ns/javaee"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee/web-facesconfig_2_2.xsd"
    version="2.2">
    <application>
        <el-resolver>org.springframework.web.jsf.el.SpringBeanFacesELResolver</el-resolver>
    </application>

    <lifecycle>
        <phase-listener>org.springframework.web.jsf.DelegatingPhaseListenerMulticaster</phase-listener>
    </lifecycle>
</faces-config>

and also changed annotations in my HelloBean, not it looks like:

@Named
@ViewScoped
public class HelloBean implements Serializable {

    private static final long serialVersionUID = 8569928214435846079L;

    public String getHello() {
        return "Hello from PrimeFaces and Spring Boot!";
    }

}

Is it a proper way to go ? Is it a good idea to use @Named instead of @ManagedBean ?
