> 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.
