Steps to reproduce:

Create a Topic or Queue but leave the "securityConfig" property empty. Then, attempt to configure the resource (eg. try changing the value of "Redelivery Delay"). The following error occurs:

15:08:32,807 INFO [NavigationContent] Resource of type [ResourceType[id=0, category=Service, name=JBoss Service (SAR), plugin=JBossAS5]] added beneath Resource [Resource[id=-3, type=JBossAS Server, key=/opt/jboss/server/default, name=JBoss AS 5 (default), parent=tomb.yyz.redhat.com, version=5.1.0.CR1]].
15:09:40,115 ERROR [ManagedComponentComponent] Failed to update configuration for ResourceType[id=0, category=Service, name=Topic, plugin=JBossAS5] Resource with key [JMSDestination:Topic:TopicNoSecConfig].
