Hi,

I am using json-path-2.4.0.

My document is the following

{
    "store": {
        "book": [
            {
                "category": "reference",
                "author": "Nigel Rees",
                "title": "Sayings of the Century",
                "price": 8.95,
                "a": {
                    "data": [
                        {
                            "foo": "bar"
                        }
                    ]
                }
            },
            {
                "category": "fiction",
                "author": "Evelyn Waugh",
                "title": "Sword of Honour",
                "price": 12.99
            },
            {
                "category": "fiction",
                "author": "Herman Melville",
                "title": "Moby Dick",
                "isbn": "0-553-21311-3",
                "price": 8.99
            },
            {
                "category": "fiction",
                "author": "J. R. R. Tolkien",
                "title": "The Lord of the Rings",
                "isbn": "0-395-19395-8",
                "price": 22.99
            }
        ],
        "bicycle": {
            "color": "red",
            "price": 19.95
        }
    },
    "expensive": 10
}

And the code is 

Configuration configuration = Configuration
            .builder()
            .mappingProvider(new JacksonMappingProvider())
            .jsonProvider(new JacksonJsonNodeJsonProvider())
            .build()
            .addOptions(Option.DEFAULT_PATH_LEAF_TO_NULL);
final DocumentContext documentContext = JsonPath
            .parse(json, configuration);

String jsonPath = "$.store.book[?('bar' in @.a.data[*].foo)].title";
Object result = documentContext.read(jsonPath);

It fails with

java.lang.ClassCastException: com.fasterxml.jackson.databind.node.ArrayNode cannot be cast to java.util.List

Any help is appreciated.

Got same problem:


JsonPath.using(Configuration.defaultConfiguration().jsonProvider(new JacksonJsonNodeJsonProvider())).parse("[{\"f1\": [1,2,3]}, {\"f1\": [4,5,6,3,2]}]").read("$[1].f1[?(@ in $[0].f1)]");
Causes error:

I have the same problem. Configurations with either JacksonJsonProvider or JacksonJsonNodeJsonProvider will throw this exception if the 'in' operator is used.

Hello! Any progress on this?

Same problem. I'm using JacksonJsonNodeJsonProvider.
