Review Comment:
   Only in AgentManager will a TaskManager object be created
       public AgentManager() {
           conf = AgentConfiguration.getAgentConf();
           agentConfMonitor = Executors.newSingleThreadExecutor();
           taskManager = new TaskManager();

Review Comment:
   > Since TaskManager is not a singleton, the static taskStore might be 
recreated multiple times.
