glassfish log

I create simple maven Enterprise Application project in NetBeans 8.0.2 with GlassFish 4.1

Session scoped managed bean:

import java.io.Serializable;
import javax.ejb.EJB;
import javax.inject.Named;
import javax.enterprise.context.SessionScoped;

@Named( value = "newJSFManagedBean" )
@SessionScoped
public class NewJSFManagedBean implements Serializable {
    @EJB
    private NewSessionBean newSessionBean;

    public NewJSFManagedBean() {
    }

    public String getName( ) {
        return newSessionBean.getName();
    }
}

and Stateless enterprise bean:

@Stateless
@LocalBean
public class NewSessionBean {

    public void businessMethod() {
    }

    public String getName() {
        return "test";
    }
}

and use this bean on jsf page:
<h:body>
    <h:outputText value="#{newJSFManagedBean.name}"/>
</h:body>

first run of this application is ok, but then i changed and save src NetBeans autoredeploy on save (+ glassfish setup checked "Preserve Sessions Across Redeployment"), and in logs appear error (in attachment file)
