@exceptionhandler not working in Spring REST

I am a beginner in Spring REST and was implementing the exception handling in Spring REST. Following is the Controller code which is throwing a custom exception

@RequestMapping(value = "/getAllCountries", method = RequestMethod.GET, headers = "Accept=application/json")
public Country getCountries() throws CountryNotFoundException{

    throw new CountryNotFoundException();

    //List<Country> listOfCountries = countryService.getAllCountries();
    // return listOfCountries;
}

@ExceptionHandler(CountryNotFoundException.class)
public ResponseEntity<ErrorMessage> handleException(HttpServletRequest req, Exception e)
{
    ErrorMessage error = new ErrorMessage("Custom handler message "+e.toString(), req.getRequestURI());
    return new ResponseEntity<ErrorMessage>(error,HttpStatus.NOT_FOUND);

}

Despite this the handler is not executing and I am getting the below exception:

HTTP Status 500 - Request processing failed; nested exception is 
org.arpit.java2blog.exception.CountryNotFoundException

Can someone please let me know are there any other configurations which need to be taken care of for the handler to execute?

EDIT: When I change the parameter for ResponseEntity to String then it works but not with ErrorMessage. Why is this behaviour happening?

Try this one

import com.fasterxml.jackson.annotation.JsonProperty;

public class ErrorMessage {

    @JsonProperty
    private final String message;

    @JsonProperty
    private final String requestURI;

    public ErrorMessage(String message, String requestURI) {
        this.message = message;
        this.requestURI = requestURI;
    }
}
