Why I'm Getting AccessControlException: access denied javax.management.MBeanPermission?

Question

I'm using glassfish 2.1.1. Sometimes I get AccessControlException: access denied (javax.management.MBeanPermission com.sun.org.apache.commons.modeler.BaseModelMBean#-[com.sun.appserv:name=HttpRequest22,type=RequestProcessor,worker=http8080] registerMBean)

Any idea what's going wrong? Is there any known issue? (I can't find any.) How can I prevent this error?
