      It was spotted in ssl failover scenario.

      • Set up balancer with 2 workers that communicate via ssl
      • Send request
      • Shutdown worker that handled the request
      • Check if everything is ok
      • Repeat

      After few failovers, undertow balancer starts to throw NPE. At this point, the worker cannot completely join with balancer and is marked as DOWN with repeating NPE showing in the balancer log. Unfortunately, there is some race condition and I cannot reproduce it efficiently. This issue comes with ssl connection as there is no NPE in non ssl failover tests.
