[rules-users] Guvnor M1 and jBOSS AS 5.1

Hi everyone, I'm having trouble deploying Guvnor M1 in jBOSS AS 5.1.0.GA. When I start the AS I become a long list of errors and at the end there is the message: DEPLOYMENTS IN ERROR: Deployment "vfsfile:/C:/Programme/JBOSS/jboss-5.1.0.GA/server/default/deploy/d rools-guvnor.war/" is in error due to the following reason(s): javax.management. InvalidAttributeValueException: Set attribute has class class org.jboss.securit y.integration.JNDIBasedSecurityManagement loaded from BaseClassLoader@113ca76{vf sfile:/C:/Programme/JBOSS/jboss-5.1.0.GA/server/default/conf/jboss-servi ce.xml} that is not assignable to attribute class interface org.jboss.security.ISecurity Management loaded from BaseClassLoader@f47144{vfsfile:/C:/Programme/JBOSS/jboss- 5.1.0.GA/server/default/deploy/drools-guvnor.war/} Do any of you know what the problem might be? best regards, Mariana
