"default" is not working inside $ref

[HemaSudha1498]

In the below example, The footerHeight is not resolved, and the default value is not set. I have approximately 50-70 properties of the same kind, all of which require default values, but duplicating the schema is not feasible.

My Schema:

{
    "$schema": "https://json-schema.org/draft-07/schema#",
    "type": "object",
    "properties": {
        "templateName": {
            "type": "string",
            "minLength": 2,
            "maxLength": 25
        },
        "headerHeight": {
            "type":"object",
            "additionalProperties": false,
            "default": {
                "units": "px",
                "value": 0
            },
            "properties": {
                "value": {
                    "type": "number"
                },
                "units": {
                    "type": "string",
                    "enum": ["px", "%"]
                }
            }
        },
        "footerHeight": {
            "$ref": "#/definitions/dimensionWithDefault"
        }
    },
    "definitions": {
        "dimensionWithDefault": {
            "type": "object",
            "additionalProperties": false,
            "default":{
                "value": 0,
                "units": "px"
            },
            "properties": {
                "value": {
                    "type": "number"
                },
                "units": {
                    "type": "string",
                    "enum": ["px", "%"]
                }
            }
        }
    },
    "required": ["templateName"]
}

My Code:

public class JsonExample {
    public static void main(String[] args) {
        JSONObject` input = new JSONObject("{\n" +
                "    \"templateName\": \"xyz\"\n" +
                "}");
        Schema schema = SchemaLoader.builder()
                .useDefaults(true)
                .schemaJson(rawSchema)
                .build()
                .load().build();

        schema.validate(input);
        System.out.println(input);
    }
}

The Output:

{
    "templateName": "xyz",
    "headerHeight": {
        "units": "px",
        "value": 0
    }
}

Kindly provide guidance on resolving this issue.

Thanks
