------------------------------------
Summary: ClassCastException in VirtualMachineManagerImpl in
handling various Agent command answer.
Key: CLOUDSTACK-7563
URL: https://issues.apache.org/jira/browse/CLOUDSTACK-7563
Project: CloudStack
Issue Type: Bug
Security Level: Public (Anyone can view this level - this is the default.)
Components: Management Server
Affects Versions: 4.3.0
Reporter: Min Chen
Assignee: Min Chen
Priority: Critical
Fix For: 4.5.0
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.
