021 * An exception listener similar to the standard <code>javax.jms.ExceptionListener</code>
022 * which can be used by client code to be notified of exceptions thrown by container components 
023 * (e.g. an EJB container in case of Message Driven Beans) during asynchronous processing of a message.
024 * <p>
025 * The <code>org.apache.activemq.ActiveMQConnection</code> that the listener has been registered with does
026 * this by calling the listener's <code>onException()</code> method passing it a <code>Throwable</code> describing
