    Description

      There is some class loading issue - when from Fabric -> Containers user tries to connect to ssh container.

      Unfortunatelly we don't have exact reproducer.
      It happens often when we have 3 member ensemble and connecting to ssh container.
      The issue usually disappears when ssh container is restarted.

      Hawtio shows Cannot Connect: org/ops4j/pax/web/service/spi/model/ServerModel

      There is following error in ssh container log:tail
