> The root cause of described above behavior is:
> First node that can't unmarshall StartRoutineDiscoveryMessage leaves
> GridContinuousHandler property as null and since StartRoutineDiscoveryMessage
> is mutable marshalls it again and sends it to the next node. So every node in
> the ring after that node can't obtain GridContinuousHandler (even it can
> properly unmarshall the message) and fails with assertion.
