[jboss-jira] [JBoss JIRA] (JBRULES-2683) DroolsSession's initWorkItemManagerFactory method can not work in a OSGi context

DroolsSession's initWorkItemManagerFactory method can not work in a OSGi context -------------------------------------------------------------------------------- Key: JBRULES-2683 URL: https://issues.jboss.org/browse/JBRULES-2683 Project: Drools Issue Type: Bug Security Level: Public(Everyone can see) Components: drools-core Affects Versions: 5.2.0.M1 Reporter: Antoine Toulme Assignee: Geoffrey De Smet Fix For: 5.4.0.CR1 This affects the current trunk. The code in the method does this: String className = this.chainedProperties.getProperty( "drools.workItemManagerFactory", "org.drools.process.instance.impl.DefaultWorkItemManagerFactory" ); [..] clazz = (Class<WorkItemManagerFactory>) Thread.currentThread().getContextClassLoader().loadClass( className ); [..] clazz = (Class<WorkItemManagerFactory>) SessionConfiguration.class.getClassLoader().loadClass( className ); None of this can work for the default factory since drools-core does not depend on drools-flow-core (and creating a dependency would create a cycle). Actually, this won't work for customer code as well, since drools-core won't depend on their bundle. I suggest to use a declarative service to work around this problem, while keeping this type of instantiation around when OSGi is not on.
