> It appears that WebBeansConfigurationListener.ensureRequestScope() is trying to make sure the requestScope is active on the thread.  Unfortunately, I believe in many cases when it isn't active, the line below with lead to a NPE:
> if (!this.lifeCycle.getContextService().getCurrentContext(RequestScoped.class).isActive())
> getCurrentContext can return null if this was called on a http request thread (for example a thread invalidating sessions), leading to an NPE when isActive() is called.
> I believe a simple fix would be to ensure the context isn't null and if it isn't null ensure it is also active.
> A sample stack trace below:
> java.lang.NullPointerException
> 	at org.apache.webbeans.servlet.WebBeansConfigurationListener.ensureRequestScope(WebBeansConfigurationListener.java:214)
> 	at org.apache.webbeans.servlet.WebBeansConfigurationListener.sessionDestroyed(WebBeansConfigurationListener.java:201)
