Keycloak is not maintaining session in browser

I am using keycloak openid-connect flow. For my client app, I am using:

public class AuthenticationTest {

public static void main(String args) {

final String KEYCLOAK_JSON = Constants.KC_CONFIG_JSON_PATH;
InputStream config = Thread.currentThread().getContextClassLoader().getResourceAsStream(KEYCLOAK_JSON);
KeycloakInstalled keycloak;

try {
keycloak = new KeycloakInstalled(config);
config.close();
keycloak.loginDesktop();

AccessToken token = keycloak.getToken();
System.out.printf("UserId: %s%n", token.getSubject());
System.out.printf("Username: %s%n", token.getPreferredUsername());
System.out.printf("Email: %s%n", token.getEmail());

System.out.println(keycloak.getTokenString());
System.in.read();
} catch (IOException | VerificationException | OAuthErrorException | URISyntaxException | HttpFailure
| InterruptedException e) {
e.printStackTrace();
}
}


}

I have referred the example mentioned here: https://gist.github.com/thomasdarimont/ca16080145d226e50628d5696ffb9508

First time I launch the application, I get

"Login Successful.You may close this browser window and go back to
your console application."

However, if I relaunch my application within just 10 seconds, even without closing the previous browser window, still the login page appears instead of : you are already logged in. (The new login page is appearing in a new tab on the same window as the first login page, so it is not an issue of failure to maintain state across different windows.)

Browser: Firefox, chrome.

Any idea what I am doing wrong. Expectation is that browser must maintain a keycloak session for the same user.
