    Description

      In the code that determines the EphemeralType it is looking at the owner (which is the client ID or connection ID):

      EphemeralType.java:

      public static EphemeralType get(long ephemeralOwner) {
      if (ephemeralOwner == CONTAINER_EPHEMERAL_OWNER)

      { return CONTAINER; }

      if (ephemeralOwner < 0)

      { return TTL; }

      return (ephemeralOwner == 0) ? VOID : NORMAL;
      }

      However my connection ID is:

      header.getClientId(): -720548323429908480

      This causes the code to think this is a TTL Ephemeral node instead of a
      NORMAL Ephemeral node.

      This also explains why this is random - if my client ID is non-negative
      then the node gets added correctly.
