SpringBoot Unable to log exception if dir in SPRING_CONFIG_ADDITIONAL_LOCATION environment not exists.

LoggingApplicationListener has lower order than EnvironmentPostProcessorApplicationListener, so if exception happens in org.springframework.boot.env.EnvironmentPostProcessorApplicationListener#onApplicationEvent shutdownHook of log4j hasn't been setup so async logger may not be able to log exceptions.

How to reproduce

SPRING_CONFIG_ADDITIONAL_LOCATION=/any/dir/not/exists java -jar application.jar with async logger.

Following stacktrace may not be able to print.
