java - Error in reading yaml file using `snakeyaml`

Question

I am getting Exception in thread "main" org.yaml.snakeyaml.error.YAMLException: java.io.IOException: Stream closed when reading yaml file in my code:

Below is my project structure:

-rc
 - main
   - java
     - MyMainClass
   - resources
     - application.yaml

Here is the sample code:

public class LoadYaml {

    private static final Logger LOGGER = LoggerFactory.getLogger(LoadYaml.class);

    public void loadYaml() {

        Yaml yaml = new Yaml(new Constructor(Config.class));
        InputStream inputStream = this.getClass()
                .getClassLoader()
                .getResourceAsStream("resources/application.yaml");
        Config config = yaml.load(inputStream);

        LOGGER.info(config.toString());
    }

Below is my custom class for yaml:

package org.finra.dapi.parttioncleanup;

import java.util.List;

public class Config {

    private String url;
    private String userName;
    private String pwsKey;
    private List<Tables> tables;

   ....getters and setters

Error stack:
