Appenders are created even if their only reference is inside of another appender that does not get referenced #806

    <appender name="inner" class="ch.qos.logback.core.rolling.RollingFileAppender">
    </appender>
    <appender name="outer" class="net.logstash.logback.appender.LoggingEventAsyncDisruptorAppender">
        <appender-ref ref="inner" />
    </appender>

Using this configuration, the RollingFileAppender gets instantiated even if the LoggingEventAsyncDisruptorAppender doesn't. This is problematic because I only ever reference the Async appender via flags that get evaluated via conditions in environments where the RollingFileAppender has permissions to create the files its referencing.

This works when using the deprecated method of nested appenders
