   Check the [`AsyncAppender` javadoc](https://logging.apache.org/log4j/1.2/apidocs/org/apache/log4j/AsyncAppender.html):
   
   > **Important note**: The AsyncAppender can only be script configured using the [DOMConfigurator](https://logging.apache.org/log4j/1.2/apidocs/org/apache/log4j/xml/DOMConfigurator.html).
   
   In the XML configuration you can use `<appender-ref ref="..."/>`.
   
   **Remark**:  Log4j 1.2 reached end-of-life almost 8 years ago. Several security vulnerabilities were discovered since then. You should **not** use it.
