Swagger parsing fails when Servers URL is set to / (default) value

As per swagger docs - https://swagger.io/docs/specification/api-host-and-base-path/

If the servers array is not provided or is empty, the server URL defaults to /

While parsing a swagger json with -

 "servers": [
    {
      "url": "/"
    }
  ],

and the java code to parse the swagger json -

OpenAPI swagger = new OpenAPIV3Parser().read(<path-to-swagger.json>);
if(swagger == null) {
	System.out.println("Swagger is null");
}

The swagger object returns null. When the server url is set to http://localhost/ the same code snippet works fine.

Swagger parser version - v3-2.1.12

Start by reproducing the issue with OpenAPIV3Parser.read using a Swagger JSON whose servers array contains {"url":"/"}, then compare it with the working http://localhost/ case. Trace the parser path for the server URL and consider the issue done when the root URL produces a non-null OpenAPI object without breaking the existing localhost case.
