> Project: Log4j 2
> Issue Type: Bug
> Components: Layouts
> Affects Versions: 2.14.1

> 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.
