The Mary TTS library is Unavailable with JDK 11. How Do I Make It Compatible?

Question

How Do I Make the Mary TTS 5.2 Library Compatible with JDK 11?

As I mentioned in the title, I need to voice a text received with the help of a CDI Bean in Turkish. This is built for a sound button that will work when the button is clicked on a web page. The problem is that Mary TTS is compatible with JDK 8 but I am using Jakarta specification and working with JDK 11. After downloading it from Mary TTS's web page, I ran it with JDK 8. The result was very good. But I couldn't get it to work in my project.

CDI Bean Code:

protected int bytesRead = 0;

public void guvenlikKodSeslendir() {
    try {
        // MaryTTS arayüzünü oluşturun
        MaryInterface maryTts = new LocalMaryInterface();

        // Türkçe yerel ayarını yükleyin
        maryTts.setLocale(new Locale("tr"));

        //Kullanılacak ses modelini ayarlayın
        maryTts.setVoice("dfki-pavoque-neutral");

        // Seslendirilecek metni ayarlayın
        String text = "Merhaba, dünya!";

        // Metni seslendirin ve ses dalgası verisini alın
        AudioInputStream audio = maryTts.generateAudio(str);

        // Ses dalgasını çalacak bir SourceDataLine oluşturun
        try (SourceDataLine line = AudioSystem.getSourceDataLine(audio.getFormat())) {
            line.open(audio.getFormat());
            line.start();
            byte[] buffer = new byte[4096];
            int bytesRead = 0;
            while ((bytesRead = audio.read(buffer)) != -1) {
                line.write(buffer, 0, bytesRead);
            }
            line.drain();
            line.stop();
        }
    } catch (IOException | LineUnavailableException | MaryConfigurationException | SynthesisException e) {
        e.printStackTrace();
    }
}

The code from the facelet page will be replaced with the "str" statement. I've corrected it for clarity.

I downloaded Mary TTS version 5.2 from mary.defki.de. I start the file "marytts-server.bat" in the "bin" folder. I also have JDK 11 version on my computer. When I start the file in this way without changing the path variable, the following error message is displayed in the console window. Output:

The above error message does not occur if JDK 8 is used.

I would like to summarize the example by making a standard class with a main method so that the subject can be better understood. Class Code:

package tr.com.fatih.beans;

import java.io.IOException;
import java.util.Locale;
import javax.sound.sampled.AudioInputStream;
import javax.sound.sampled.AudioSystem;
import javax.sound.sampled.LineUnavailableException;
import javax.sound.sampled.SourceDataLine;
import marytts.LocalMaryInterface;
import marytts.exceptions.MaryConfigurationException;
import marytts.exceptions.SynthesisException;

public class MaryTTSExample {
    public static void main(String[] args) {
        try {
            LocalMaryInterface maryTts = new LocalMaryInterface();
            maryTts.setLocale(new Locale("tr"));
            maryTts.setVoice("dfki-pavoque-neutral");
            String text = "Merhaba, bu bir deneme metnidir.";
            AudioInputStream audio = maryTts.generateAudio(text);
            try (SourceDataLine line = AudioSystem.getSourceDataLine(audio.getFormat())) {
                line.open(audio.getFormat());
                line.start();
                byte[] buffer = new byte[4096];
                int bytesRead = 0;
                while ((bytesRead = audio.read(buffer)) != -1) {
                    line.write(buffer, 0, bytesRead);
                }
                line.drain();
                line.stop();
            }
        } catch (IOException | IllegalArgumentException | LineUnavailableException | MaryConfigurationException | SynthesisException e) {
            e.printStackTrace();
        }
    }
}

NetBeans gives me a warning when I run the code.
