[jboss-jira] [JBoss JIRA] (DROOLS-56) Error with Bundle activator of org.kia-api - NPE when we stop it

[Charles Moulliard (JIRA)]

    [ https://issues.jboss.org/browse/DROOLS-56?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12757080#comment-12757080 ] 

Charles Moulliard commented on DROOLS-56:
-----------------------------------------

Error comes from the fact that the ServiceRegistry has not been instantiated in the start method

{code}
// @TODO (mdp) commented t allow it to compile
//        this.serviceRegistry = bc.registerService( ServiceRegistry.class.getName(),
//                                                   ServiceRegistryImpl.getInstance(),
//
//                                                   new Hashtable() );

    public void stop(BundleContext bc) throws Exception {
        this.serviceRegistry.unregister(); NPE occurs here
        this.registryTracker.close();
        this.marshallerProviderTracker.close();
    }

So we have to comment it for the moment

//         this.serviceRegistry.unregister();

{code}
