> If a {{ContainerExecutionException}} is thrown during container launch under 
> LCE information is added to the diagnostics for the container regarding the 
> failure. The diagnostic's output includes the container id, exit code, "error 
> output" and "shell output", with the expectation that the relevant exception 
> details are in the "error output". 
> {{ContainerExecutionException}} has several constructors, with the most 
> commonly used being the one that accepts a String. This form does not put the 
> exception details into the "error output". This makes it difficult for the 
> user to troubleshoot the failure.
