Hi Thanuja,
I was referring to the build fail in [1]. Please see line starting from:
2015-10-02 07:28:32 INFO
{org.wso2.carbon.automation.extensions.servers.utils.ServerLogReader}:70 -
[2015-10-02 07:28:32,834] ERROR
{org.apache.stratos.autoscaler.rule.RuleTasksDelegator} - Cannot terminate
instance
I think this is a separate issue that occurs very rarely. As you noticed,
NPE in GroupMonitor occurs when undeploying applications. The problem is
group monitors are retrieving the status from other group monitor objects.
@Reka: shall we change that logic to read the application status from
topology or ApplicationHolder instead of reading from monitors?

Thanks.
