Fabric Container discovery fails in JBoss ON with Exception: java.util.UnknownFormatConversionException: Conversion = '%'

Issue

• We uninventoried platform and tried to discover it and add to the inventory again - but discovery of the Fabric Container fails;
• Our Fabric Container is not discovered as a Fuse ESB Container. How can we correct this?
• Discovery of the Fabric Container fails in JBoss ON with the following Exception:

DEBUG [ResourceDiscoveryComponent.invoker.daemon-1] (org.jbosson.plugins.fuse.FabricContainerDiscoveryComponent)- Found Fabric Container with container name: test-container
