Effect observed: Intermittent JSF bootstrapping failure on AS7

JSF automatically adds the faces servlet using a ServetContextInitalizer, as does seam faces. If Seam Faces SCI runs before the JSF one, deployment will fail. This is because of some weirdness in the JSF impl, where it checks is faces is enabled by looking in web.xml for the servlet, and checks if the com.sun.faces.facesInitializerMappingsAdded is set to true (this is set by the Faces SCI when it adds the servlet).

If the faces SCI runs first the JSF SCI will see the servlet as being registered and return, and then the JSF initialiser code will not see the programatically registered servlet and will not bootstrap JSF.

For now a work around would be to have the Seam Faces SCI set the servlet context attribute com.sun.faces.facesInitializerMappingsAdded to true.

Sometimes the application deployment fails with

No further information is display. Sometimes a re-deploy helps, sometimes a reboot of the server, sometimes neither. The application worked fine on AS6
