{code}
*Analysis*
Looks like for absent container also {{stopContainer}} is called
{code}
case CONTAINER_FINISHED:
LogHandlerContainerFinishedEvent containerFinishEvent =
(LogHandlerContainerFinishedEvent) event;
stopContainer(containerFinishEvent.getContainerId(),
containerFinishEvent.getExitCode());
break;
{code}
Should skip when {{null==context.getContainers().get(containerId)}}
