OTEL logback appender ignores additivity?

[den850x]

My logback.xml defines a custom logger that has additivity="false", and the OtelAppender is configured for the root only.
But the messages logged to MyPrivateLogger are still getting picked up by OtelAppender.
Is this expected?

 <logger name="MyPrivateLogger" additivity="false" level="INFO">
        <appender-ref ref="Console"/>
 </logger>

  <root level="INFO">
    <appender-ref ref="OtelAppender"/>
  </root>

Please provide a minimal application that reproduces your issue.

Turned out, my issue was caused by running both OTEL Logback Appender and OTEL JavaAgent. The latter had logback integration enabled by default.

The log output from MyPrivateLogger was picked up by the OTEL Java Agent.
I've disabled its logback integration by setting otel.instrumentation.logback-appender.enabled=false, so now I only have OTEL Logback Appender running in my app. This fixed my issue.

Sorry for the confusion!
