2014-03-13 15:12:35 PDT [org.apache.catalina.core.ContainerBase.[Catalina].[localhost].[/restconf].[JAXRSRestconf]] SEVERE org.apache.catalina.core.StandardWrapperValve invoke Servlet.service() for servlet [JAXRSRestconf] in context with path [/restconf] threw exception [java.util.concurrent.ExecutionException: java.lang.IllegalStateException:
If a YANG Model contains a leaf of type enumeration, like this:

leaf node-connector-type {
type enumeration {
enum "CTRL"

{ value 0; description "Represents the OFPP_CONTROLLER reserved port to forward a packet to the controller, this is to send data packets to the controller from the data plane triggering a packet_in event."; }

enum "ALL"

{ value 1; description "Represents the OFPP_ALL reserved OF port to forward to ALL the ports in the system , should be used for flooding like mechanism to be used cautiously to avoid excessive flooding."; }

And the value is passed in via RestConf as let's say "ALL", then YANGTools fails with the following ClassCastException.
