> I get a NullPointerException when trying to inject a logger into my code. It happens in two circumstances - once when injection is done by the container, once when I manually inject (using the SPI of course!).
> The top of the stack trace is exactly the same in both instances:
> java.lang.NullPointerException org.jboss.weld.util.Beans.isPassivatingScope(Beans.java:132) org.jboss.weld.bean.AbstractProducerBean.checkReturnValue(AbstractProducerBean.java:263) org.jboss.weld.bean.AbstractProducerBean.create(AbstractProducerBean.java:349) org.jboss.weld.context.DependentContext.get(DependentContext.java:62) org.jboss.weld.manager.BeanManagerImpl.getReference(BeanManagerImpl.java:788) org.jboss.weld.manager.BeanManagerImpl.getReference(BeanManagerImpl.java:850) org.jboss.weld.manager.BeanManagerImpl.getInjectableReference(BeanManagerImpl.java:874) org.jboss.weld.injection.FieldInjectionPoint.inject(FieldInjectionPoint.java:108) org.jboss.weld.util.Beans.injectBoundFields(Beans.java:775) org.jboss.weld.util.Beans.injectFieldsAndInitializers(Beans.java:787) org.jboss.weld.manager.SimpleInjectionTarget$1.proceed(SimpleInjectionTarget.java:122) org.jboss.weld.injection.InjectionContextImpl.run(InjectionContextImpl.java:51) org.jboss.weld.manager.SimpleInjectionTarget.inject(SimpleInjectionTarget.java:116) 
> The code fragment for the item being injected is the following: (the logger is a log4j logger)
> public class LoggingFactory {
>     @Produces
>     Logger createLogger(InjectionPoint injectionPoint) {
> 	return Logger.getLogger(injectionPoint.getMember().getDeclaringClass().getName());
>     }
> }
> The servletContextListener code fragment is as follows:
> public class ApplicationInitialisation
> 	implements ServletContextListener {
>     @Inject
>     private Logger log;
>     /**
>      * @see ServletContextListener#contextInitialized(ServletContextEvent)
>      */
>     public void contextInitialized(ServletContextEvent event) {
>         // Never gets into the method because of the stack trace
>     }
