ServiceRegistry references non existent classes ----------------------------------------------- Key: DROOLS-1442 URL: https://issues.jboss.org/browse/DROOLS-1442 Project: Drools Issue Type: Bug Reporter: Anton Giertli Assignee: Mario Fusco Fix For: 7.0.0.CR1 This code {code:java} SystemEventListener listener = SystemEventListenerFactory.getSystemEventListener(); {code} Fails with: Caused by: java.lang.ClassNotFoundException: org.drools.core.impl.SystemEventListenerServiceImpl Because ServiceRegistryImpl https://github.com/droolsjbpm/droolsjbpm-knowledge/blob/master/kie-intern... references class SystemEventListenerServiceImpl which does not exist anymore in drools-core. The interface SystemEventListenerService still exists in kie-internal but there is no implementation whatsoever in drools. First impression is that both SystemEventListenerService + SystemEventListenerServiceImpl are "dead" code and should probably be removed.
