In r12.0 System Agent job fails when (.) dot is prefixed in command field.
command: . /tmp/abc.sh
Release : 12.0
Component : Workload Automation System Agent
In r12.0 currently the Agent is treating any string before space as command and any string after space as argument. In this case dot (.) is considered as a command and hence it is failing.
