Schema is not properly validating data

[deep9]

What version of Ajv are you using? Does the issue happen if you use the latest version?
4.11.3, latest at the time

Ajv options object (see https://github.com/epoberezkin/ajv#options):

{allErrors: true, removeAdditional: 'all'}

JSON Schema (please make it as small as possible to reproduce the issue):

{
  "$schema": "http://json-schema.org/draft-04/schema#",
  "id": "testDefinitions",
  "description": "Test definition schema",

  "type": "array",

  "items": {
    "type": "object",
    "anyOf": [
      {
        "allOf": [
          {
            "allOf": [
              {
                "properties": {
                  "type": {
                    "type": "string",
                    "minLength": 1
                  }
                }
              },
              {
                "required": [
                  "type"
                ]
              }
            ]
          },
          {
            "properties": {
              "type": {
                "enum": [
                  "openUrl"
                ]
              },
              "lineId": {
                "type": "string"
              },
              "url": {
                "type": "string",
                "format": "uri",
                "minLength": 1
              }
            },
            "required": [
              "url"
            ]
          }
        ]
      }
    ]
  }
}

Please note the schema is dereferenced, that is why there is a lot of allOf elements

Data (please make it as small as posssible to reproduce the issue):

[
	{
		"lineId": 1,
		"type": "openUrl",
		"url": "http://localhost"
	}
]

Your code (please use options, schema and data as variables):

const ajv = new Ajv(options);
return new Promise((resolve, reject) => {
        ajv.validate(schema, data);
        if (ajv.errors === null) {
            resolve(data);
        } else {
            reject(ajv.errors);
        }
    });

See: https://runkit.com/deep9/ajv-issue

Validation result, data AFTER validation, error messages:

[ { keyword: 'required',
    dataPath: '[0]',
    schemaPath: '#/items/anyOf/0/allOf/1/required',
    params: { missingProperty: 'url' },
    message: 'should have required property \'url\'' },
  { keyword: 'anyOf',
    dataPath: '[0]',
    schemaPath: '#/items/anyOf',
    params: {},
    message: 'should match some schema in anyOf' } ]

What results did you expect?
If you run the same schema in http://www.jsonschemavalidator.net, expected result of

Message:
JSON does not match any schemas from 'anyOf'.
Schema path:
testDefinitions#/items/0/anyOf
Message:
JSON does not match all schemas from 'allOf'. Invalid schema indexes: 1.
Schema path:
testDefinitions#/items/0/anyOf/0/allOf
Message:
Invalid type. Expected String but got Integer.
Schema path:
testDefinitions#/items/0/anyOf/0/allOf/1/properties/lineId/type

Are you going to resolve the issue?
Don't know how.

[epoberezkin]

The reason is removeAdditional options, when the first subschema is validated everything but "type" gets removed.

see #129, https://github.com/epoberezkin/ajv/blob/master/FAQ.md#additional-properties-inside-compound-keywords-anyof-oneof-etc

Now I've tested with https://pypi.python.org/pypi/jsonschema and the result is the same. As being new to json schema, how can I know which one is correct?
