5.0.0: applet fails to initialize with default log4j.properties.
----------------------------------------------------------------

                 Key: AMQ-1605
                 URL: https://issues.apache.org/activemq/browse/AMQ-1605
             Project: ActiveMQ
          Issue Type: Bug
          Components: JMS client
    Affects Versions: 5.0.0
         Environment: jre 1.6.0_03 applet on both firefox and msie.
            Reporter: Bear Giles


We are unable to create a JMS-aware applet because of an initialization error in ActiveMQConnectionFactory/ActiveMQConnection.
 My research suggests that the problem is due to a static logger instance and a default log4j.properties
file that contains an appender that is inappropriate (as in, throws security exceptions) in
applets.
