In r12.0 System Agent job fails when (.) dot is prefixed in command field.
command: . /tmp/abc.sh
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.
Release : 12.0
Component : Workload Automation System Agent
