When a status listener is registered by setting the "logback.statusListenerClass" Java system property, such as

java -Dlogback.statusListenerClass=ch.qos.logback.core.status.OnConsoleStatusListener ...

AND

The logback configuration file is set to automatically re-configure, such as

<configuration scan="true">
...
</configuration>

The registered status listener is lost and not re-established whenever the configuration file is reloaded due to a detected change.
