PATCH with "target":"/" error

Beryllium bug, this is what happens when attempting to replace the whole car:cars container:

$ curl -u'admin:admin' -X PATCH -H "Content-Type:application/yang.patch+json" -d '{"ietf-restconf:yang-patch":{"patch-id":"0","edit":[{"edit-id":"0","operation":"replace","target":"/","value":{"car:cars":{"car-entry":[

]}}}]}' 127.0.0.1:8181/restconf/config/car:cars ;echo

{"errors":{"error":[{"error-type":"protocol","error-tag":"malformed-message","error-message":"Error parsing json input: Could not parse Instance Identifier '/car:cars/'. Offset: 10 : Reason: Identifier cannot end with '/'.","error-info":"java.lang.IllegalArgumentException: Could not parse Instance Identifier '/car:cars/'. Offset: 10 : Reason: Identifier cannot end with '/'.\n\tat com.google.common.base.Preconditions.checkArgument(Preconditions.java:145)\n\tat org.opendaylight.yangtools.yang.data.util.XpathStringParsingPathArgumentBuilder.checkValid(XpathStringParsingPathArgumentBuilder.java:255)\n
(and so on)
