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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
