Solution for signer information error (occuring at server startup or on browsing) for ATG 10.1 CRS

I have configured CRS (Commerce Reference Store) for ATG 10.1 using CIM (Configuration and Installation Manager). After server startup I tried to browse the application but only header was displaying.Server was throwing below exception.

ERROR [[jsp]] Servlet.service() for servlet jsp threw exception java.lang.SecurityException: class "atg.commerce.order.OrderHolder$$EnhancerByCGLIB$$e9ab456d"'s signer information does not match signer information of other classes in the same package

Solution :  Replace the jboss-eap-5.0/jboss-as/common/lib/cglib.jar with the unsigned version, which can be downloaded from the following URL : http://repository.jboss.com/maven2-brew/cglib/cglib/2.2/cglib-2.2.jar or http://search.maven.org/remotecontent?filepath=cglib/cglib/2.2.2/cglib-2.2.2.jar.
This is due to a problem with the JBoss cglib library.For more details see the JBoss bug https://jira.jboss.org/jira/browse/JBPAPP-2971.
