> I'm not sure if this is just faulty test/edge case/WFLY/EAP integration failure, but there is case when org.apache.tomcat.websocket.server.WsSci is scheduled and triggered twice. This makes WsServerContainer throw NPE, since servletContext.addFilter[1] return null if filter with specified name exist.
> Regardless this case being a valid one or not, WsServerContainer should handle this either with proper message or different exception than NPE.
> I'm assigning this to myself for time being( until I can establish if WFLY/EAP being at fault and procure testcase )
