The app's web.xml contains the following listeners:

org.jboss.weld.environment.servlet.BeanManagerResourceBindingListener
com.sun.faces.config.ConfigureListener

The first listener registers BeanManager with JNDI. The second listener initializes JSF and looks up for BeanManager in the JNDI.

This setup works perfectly ok when jetty maven plugin runs with "jetty:run-war" goal or when the application is running as standalone with embedded jetty.

However when running it with "jetty:run" goal the BeanManager registered in the first listener is not visible in the JSF resulting in NPE's on session invalidation/destruction of the ViewScoped beans.

NPE stack trace:
