json-patch schema can't be even loaded

[s13o]

Just try to load a json schema from http://json.schemastore.org/json-patch by 'SchemaLoader.load'
The exception is

org.everit.json.schema.SchemaException: #/definitions/operation: expected at most 1 of 'allOf', 'anyOf', 'oneOf', 2 found

Sad. If it helps, rewriting the schema this way should work (didn't test it):

{
    "$schema": "http://json-schema.org/draft-04/schema#",
    "definitions": {
        "operation": {
            "allOf": [
                {
                    "allOf": [
                        {
                            "$ref": "#/definitions/path"
                        }
                    ]
                },
                {
                    "oneOf": [
                        {
                            "properties": {
                                "op": {

}

Fixing the real issue (properly loading multiple combined schemas at the same nesting level) might not come any soon.
