JsonParseException на клиенте Jsonrpc4j

Question

Я пытаюсь создать клиент с jsonrpc4, но у меня всегда есть ошибка JsonParseException. Я пробовал много вещей, простой client.invoke и динамический прокси, но он не работает, и я не понимаю, почему.

Есть мой код

public static void main(String[] args) throws Throwable {
        try {
            String username = "****";
            String password = "****";
            String cred = Base64.encodeBytes((username + ":" + password).getBytes());

            Map<String, String> headers = new HashMap<>(1);
            headers.put("Authorization", "Basic " + cred);

            JsonRpcHttpClient client = new JsonRpcHttpClient(new URL("https://dms1.ok.by/api/v1/json­rpc"));
            String elem =  client.invoke("myMethod", new Object [] {"param"}, String.class);

        }
        catch(Throwable throwable) {
            throwable.printStackTrace();
        }
    }

И вот мои подробности ошибки: com.googlecode.jsonrpc4j.HttpException: поток закрыт на com.googlecode.jsonrpc4j.JsonRpcHttpClient.invoke(JsonRpcHttpClient.java:161) на com.googlecode.jsonrpc4j.Jttp.jp.jp.jp.jp 185) в com.googlecode.jsonrpc4j.JsonRpcHttpClient.invoke(JsonRpcHttpClient.java:110) в net.nameshield.registryapi.monRobot.main(monRobot.java:38).

Большое спасибо я тебе могу помочь, я злюсь:D
