            }
        }
    }
</pre>
</div></div>

<p>Even if SiftingAppender would work (I suspect it doesn't because of a combination of timeout I've specified, frequency of the FINALIZE_SESSION markers sent, and actual append calls), it would not fit my needs as in our app we actually need to close the appender immediately, without any lingering or timeout.</p>

<p>I'd suggest to support this (immediate close) when timeout option is set to 0.</p>

<p>Another issue I've ran into is that JoranConfigurator uses its own ClassLoader to load classes, and as our code is a plugin loaded by a host app and JoranConfigurator is used by the host app and is already loaded, I couldn't specify a custom appender in the logback.xml and have to configure Loggers at runtime, programmatically.</p></div>
