> How to reproduce:
>  # Generate a LogEvent with an Exception that has at least one cause (i.e. nested Exception)
>  # Use the standard JSON Layout to turn that LogEvent into JSON
>  # Using JsonLogEventParser to turn it back into a LogEvent
>  # Call getExtendedStackTraceAsString() on the ThrowableProxy associated with the deserialized LogEvent
>  # A NullPointerException will be thrown
> I've attached a small example project to reproduce the error.
