java.lang.IllegalStateException: Duplicate key

[mraalex]

On Android I get a duplicate key exception when I want to list the countries. I can also provide a sample project in case you can not reproduce it.

                    System.setProperty("jakarta.ws.rs.client.ClientBuilder", "org.glassfish.jersey.client.JerseyClientBuilder");
                    RadioBrowser browser = new RadioBrowser(5000, "Demo agent/1.0");
                    browser.listCountries();

New release 2.3.1 fixing this should be in maven repos soon:
