* PatternLayout actually handles exceptions, when in fact it does not.
* By adding %nopex to the conversion pattern, the user can bypass
* the automatic addition of %ex conversion pattern for patterns
* which do not contain a converter handling exceptions.

Users can ignore the existence of this converter, unless they
* want to suppress the automatic printing of exceptions by
* {@link PatternLayout}.
