I am using slf4j and logback version 1.3.14 and removed an appended, but failed to remove the corresponding from the element. Logback was started, and no error was thrown. For all other appenders in the -element the log files were created, but the log files are empty.

<root level="INFO">
        <appender-ref ref="DEFAULT-FILE"/>
        <appender-ref ref="SECURITY-FILE"/>
        <appender-ref ref="NON-EXISTENT-FILE"/>
</root>

I know that this is a configuration issue. It would be good if an error or a warning message is thrown if an appender-ref is used for a non-existent appended.

Thanks

The corresponding log:
