RestConf returns full class name for identity item

I modeled following model using identity

identity group-type

{ description "Base identity for all the available group types"; }

identity group-all

{ base group-type; description "All (multicast/broadcast) group"; }

grouping group-features {

leaf-list group-types-supported {
type identityref

{ base group-type; }

}
}

When i fetch these group-features through RestConf, it shows me full class name with package string as follows

<group-types-supported>class org.opendaylight.yang.gen.v1.urn.opendaylight.group.types.rev131018.GroupAll</group-types-supported>
