I have downloaded the latest version and ran the window installer.  

Where I start the server up, an error displays involving the log4j component.  I have not changed the log4j.xml settings, so I am confused why this error would even happen:

  | 20:05:44,757 ERROR [STDERR] log4j:ERROR A "org.jboss.logging.util.OnlyOnceErrorHandler" object is not assignable to a "org.apache.log4j.spi.ErrorHandler" variable.
  | 20:05:44,757 ERROR [STDERR] log4j:ERROR The class "org.apache.log4j.spi.ErrorHandler" was loaded by 
  | 20:05:44,757 ERROR [STDERR] log4j:ERROR [WebappClassLoader
  |   delegate: false
  |   repositories:
  |     /WEB-INF/classes/
  | ----------> Parent Classloader:
  | java.net.FactoryURLClassLoader at 31c43f
  | ] whereas object of type 
  | 20:05:44,757 ERROR [STDERR] log4j:ERROR "org.jboss.logging.util.OnlyOnceErrorHandler" was loaded by [org.jboss.system.server.NoAnnotationURLClassLoader at ab95e6].
  | 20:05:44,820 ERROR [STDERR] log4j:ERROR Could not create an Appender. Reported error follows.
  | 20:05:44,820 ERROR [STDERR] java.lang.ClassCastException: org.jboss.logging.appender.DailyRollingFileAppender

I checked to ensure I had the log4j.jar (or something like it) within the server area.  I found log4j-boot.jar found in <JBOSS_DIR>/lib, so I am at a lost to explain why there is an issue.

Can someone shed some light on this for me?
