When logging some events the application needs to be informed that the publishing of the event failed. Currently, AppenderBase and UnsynchronizedAppenderBase catch and handle all exceptions making it impossible to use any of the out-of-the box Logback appenders in these situations. This is particularly important when performing auditing and sending the events to a database, JMS queue, socket, etc. as the application would want to fail the current operation if it cannot be audited.
