When action called AgentListener automatically starts listening upon first EP send to the agent. But Environment.deploy() were the only place where AgentLister was stopped. So when action other than Environment.deploy() was called there is no one to stop listener. Thus on each action call new listener on the same RabbitMQ queue was started causing listeners to steal messages from each other. Agent.call() that never received response from agent caused deployment/action hang. Change-Id: Ia778c816a0e2f57d1f694fd1f128848f61b21a2d Closes-Bug: #1425963
