             Summary: Failover appender doesn't fail over on JMS Queue appender error
                 Key: LOG4J2-126
                 URL: https://issues.apache.org/jira/browse/LOG4J2-126
             Project: Log4j 2
          Issue Type: Bug
          Components: Appenders
    Affects Versions: 2.0-beta4
            Reporter: Szabolcs Beki


My goal is to send log messages via a JMS Queue unless the message broker is down, \
when I simple want send the logs to the Console.

I configured a failover appender for this purpose:
 : 
<appenders>

...

		<JMSQueue name="LiffLog4j2Queue" queueBindingName="Log4j2Queue" \
factoryBindingName="QueueConnectionFactory"/>  <Failover \
name="FailoverLiffLog4j2Queue" primary="LiffLog4j2Queue" suppressExceptions="false">  \
<Failovers>  <appender-ref ref="Console"/>
			</Failovers>
		</Failover>
	</appenders>
	<loggers>
		<root level="debug">
			<appender-ref ref="FailoverLiffLog4j2Queue"/>		
		</root>

All works as expected when the message broker is up. 

When I shut down the message broker while running my application, instead of the log \
message  I get this message to my console : 2012-11-21 21:51:15,726 ERROR Could not \
publish message via JMS JMSQueue:QueueConnectionFactory.Log4j2Queue 


Using a failover appender I expected to get the log messages on the console.

Also tried to start my application without ever starting message broker. In this case \
it correctly fails to connect :

BUT shortly afterwards my application exits with : 

2012-11-21 22:10:10,238 ERROR Unable to locate primary Appender LiffLog4j2Queue
2012-11-21 22:10:10,239 DEBUG Reconfiguration completed

org.apache.logging.log4j.core.config.AppenderControl.callAppender(AppenderControl.java:88)
  at org.apache.logging.log4j.core.config.LoggerConfig.callAppenders(LoggerConfig.java:335)


As it can not find primary appender (JMSQueue) it can not start the failover appender \
either.
