-----------------------------------------------------------------------
Its probably a chicken/egg problem.
JSF (both Mojarra and MyFaces) are developed with the background that CDI has
to be initialized before starting the servlet context.
So it's IMO up to Wildfly as the initial deployment is also correct. Not sure
whats wrong on restart/redeploy but thats really Wildfly related.
Will close it for now. Please create a issue on their side.
