IllegalStateException thrown during deployment when processing EJB metrics on .ear that contains beans with same name in different ejb.jars

Test archive:
JBPAPP_5_0/testsuite/output/lib/refspath.ear

This ear contains two ejb.jars:
refspath-ejb1.jar
refspath-ejb2.jar

The ejb class names within the .jars are unique but they use the same name; i.e.,
@Stateless(name = "EJB")

causing the deployment to fail as the refspath.ear-EJB-metrics-instance is "already installed".
