Component schemas with same name are ignored after the second one

[BabisK]

When several referenced schemas have the same name but different definitions, only the first two are created in components/schemas, the rest are ignored.

main.java

import io.swagger.v3.oas.models.OpenAPI;
import io.swagger.v3.parser.core.models.ParseOptions;

public class Main {

    public static void main(String[] args) {
        ParseOptions options = new ParseOptions();
        options.setResolve(true);
        OpenAPI openAPI = new OpenAPIV3Parser().read("base.yaml", null, options);
        System.out.println(openAPI.getComponents().getSchemas().keySet());
    }
}

Result

[body, body_2]

Expected result

[body, body_1, body_2]

Note: In this case 3 schemas are expected since POST.type3.body and POST.type4.body have the same definition.
