MapperParsingException[failed to parse]; nested: NoSuchMethodError

[FabienO]

Adding images seems to return an error. I can't index anything.

curl -XPOST 'localhost:9200/test/test' -d '{ "my_img": "iVBORw0KGgoAAAANSUhEUgAAAAsAAAALCAYAAACprHcmAAAAX0lEQVQYlZWRYQrAIAiFNQ/j6T2ev10v2HDTQQmPyD6foUTv4KmRxPQTeJRGowVVVcxM3H2duH8L+AYjoigV8OMKpw5GPrsvGK07GPkC7zof/floGltznl3KYtoNAoQuatt0CKG31GsAAAAASUVORK5CYII=" }';

{
    "error": "MapperParsingException[failed to parse]; nested: NoSuchMethodError[org.elasticsearch.index.mapper.ParseContext.externalValue(Ljava/lang/Object;)V]; ",
    "status": 400
}

Using es version 1.5.0 on Centos 7

Here's my mapping for confirmation

{
    "test": {
        "mappings": {
            "test": {
                "properties": {
                    "my_img": {
                        "type": "image",
                        "feature": {
                            "JCD": {
                                "hash": [
                                    "BIT_SAMPLING",
                                    "LSH"
                                ]
                            },
                            "FCTH": {},
                            "CEDD": {
                                "hash": [
                                    "BIT_SAMPLING"
                                ]
                            }
                        },
                        "metadata": {
                            "jpeg.image_height": {
                                "type": "string",
                                "store": true
                            },
                            "jpeg.image_width": {
                                "type": "string",
                                "store": true
                            }
                        }
                    }
                }
            }
        }
    }
}

And the plugins for the node show the plugin for "image" added.

I'm pretty sure it's probably me doing something dumb, can you provide any help advice if so?

Downgraded elastic search to similar version used in examples and it works.
