> We have been seeing issues with our automated tests failing in a farm
> environment due to a valid FacesContext not being available for a request,
> particularly for a request for a resource. The logs show the following errors
> when this happens:
> FacesContext: com.sun.faces.config.InitFacesContext@1b5e765
> ServletContext: null
> java.lang.NullPointerException

> We could trace this back to some variant of the following implementation
> issue in Mojarra runtime.
> https://java.net/jira/browse/JAVASERVERFACES-2533
> The issue is that the FacesContext is not being cleaned up properly, so new
> requests could get hold of an invalid but non null FacesContext hanging
> around.
> A solution for this is for the ResourceServlet to check and see if we have a
> bogus FacesContext, in which case, discard it and recreate a good one. The
> suggested code change is a simple addition to an existing code that checks
> for a non-null FacesContext.
