Recursive schema $ref generates an extra class

[rpatrick00]

I am trying to create a schema for a recursive etcd directory listing. From what I can tell, it should look something like this:

{
    "id": "EtcdDirectoryListing",
    "$schema": "http://json-schema.org/draft-04/schema#",
    "description": "The etcd Manifest used for recursive directory listings",
    "type": "object",
    "properties": {
    "action": { "type": "string" },
    "node": {
        "id": "EtcdNode",
        "description": "Etcd key-value node",
        "type": "object",
        "properties": {
        "key": { "type": "string" },
        "dir": { "type": "boolean" },
        "nodes": {
            "type": "array",
            "items": {
            "$ref": "#/properties/node"
            }
        },
        "modifiedIndex": { "type": "integer" },
        "createdIndex": { "type": "integer" }
        }
    }
    }
}

The problem I am having is that the Maven plugin is generating both a Node.java and a Node_.java class. I was expecting it to generate a single Node.java class that contains a List element in it. I assume that I am doing something stupid so any help would be appreciated.

This is same as #481. Possible solution is proposed in its description.
