Issue

  • Two war files have the same JPA persistence unit named "drift" deployed in their WEB-INF/lib directory.  When these war files are deployed to the same JBoss instance the following exception is thrown.
        Unable to register deployment mbean org.jboss.metadata.jpa.spec.PersistenceUnitMetaData.drift
        javax.management.InstanceAlreadyExistsException: jboss.deployment:id="org.jboss.metadata.jpa.spec.PersistenceUnitMetaData.drift",type=Component already registered.
