> irtualMachineManagerImpl has many methods directly cast the Answer received from AgentManager.send or AgentManager.easySend to the expected Answer class in the normal case. This will throw unhandled  ClassCastException in some unexcepted cases where host is down and agent is disconnected, which will lead to cloud instability.
