22   * Thrown from an appender when a log event could not be written. Appenders should not thrown an exception if an error
23   * occurs that does <em>not</em> stop the event from being successfully written. Those types of errors should be logged
24   * using the {@link org.apache.logging.log4j.status.StatusLogger}. Appenders should only throw exceptions when an error
25   * prevents an event from being written. Appenders <em>must</em> throw an exception in this case so that error-handling
26   * features like the {@link FailoverAppender} work properly.
27   *
28   * Also note that appenders <em>must</em> provide a way to suppress exceptions when the user desires and abide by
29   * that instruction. See {@link org.apache.logging.log4j.core.Appender#ignoreExceptions()}, which is the standard
30   * way to do this.
