> When a container crashes, ExitCodeException will be thrown from Shell. Default/LinuxContainerExecutor captures the exception, put the exception stack into the diagnostic. Therefore, the exception stack is always the same. 
> {code}
>         String diagnostics = "Exception from container-launch: \n"
>             + StringUtils.stringifyException(e) + "\n" + shExec.getOutput();
>         container.handle(new ContainerDiagnosticsUpdateEvent(containerId,
>             diagnostics));
> {code}
> In addition, it seems that the exception always has a empty message as there's no message from stderr. Hence the diagnostics is not of much use for users to analyze the reason of container crash.
