> Affects Versions: 2.14.1
> Environment: Spring Boot 2.5.4

> * Full exception printed to buffer in
> org.apache.logging.log4j.core.pattern.Throwable
> * PatternConverter#formatOption().
> * Full exception still in buffer after next and final formatter runs
> (LineSeparatorPatternConverter) in file PatternLayout.
> * Then some kind of encoding logic happens and what is printed to Console is
> the truncated exception.
