JSON Parser does not correctly parsed choice inside augmentation.

I set the severity of this bug to blocker, because we cannot finish our Hackathon demo setup, until following issue will be solved:

Given this augmentation (sfc-model/src/main/yang/service-function-acl.yang):

augment "/ietf-acl:access-lists/ietf-acl:access-list/ietf-acl:access-list-entries/ietf-acl:actions" {
description "SFC simple filter actions";
choice sfc-action {
case acl-rendered-service-path {
description "Determine the Service Function Path the packet the packet will
traverse";
leaf rendered-service-path

{ type string; }

}
}
}

I can PUT and then GET data throught RESTconf including the augmentation leaf:

{
"access-lists": {
"access-list": [
{
"acl-name": "ACL1",
"access-list-entries": [
{
"rule-name": "ACE1",
"actions":

{ "service-function-acl:rendered-service-path": "SFC1-SFP1" }

}
]
}
]
}
}

The issue occurs, when I get Listener notification, with corresponding DataObject actions:

Actions1 actions1 = actions.getAugmentation(Actions1.class);

actions1 will be always null, even the augmentation data are present (as verified through RESTconf)
