Failed to find factory for event

[simps05192]

JBoss 4.0.0RC1, Windows XP

I'm getting errors of the form

17:36:50,718 DEBUG [DefaultManagedObjectFactoryMap] Failed to find factory for event: javax.management.Notification[source=jboss.system:service=ServiceController,type= org.jboss.system.ServiceMBean.create,sequenceNumber=7,timeStamp=1095467810718,message=null,userData=jboss.management.local:j2eeType=J2EEDomain,name=Manager]

in the boot.log when I start up. How can I prevent this error and is it harmful?

Its not an error as its logged at DEBUG level. Set the log4j category filter to INFO or higher on the org.jboss.management.j2ee.factory category.
