Weird classname while saving FileConfiguration.save()

Hi All, I'm new at Java and Plugin Development,
I'm facing a problem while saving the config.yml for first time, after plugin loads it doesn't save config.yml properly, after load if I run reload command on my server, config.yml fixes itself.

Here is my first load config.yml

Code:

# Serhat KAYA

cleaner: !!serhatkaya.candieUtils.types.CleanerSettings
  enabled: true
  messages:
    cleanSucceed: Cleaned successfully
    fiveToClean: The items on the ground will be removed in 10 seconds.
    tenToClean: The items on the ground will be removed in 10 seconds.
  offset: 60
broadcaster: !!serhatkaya.candieUtils.types.BroadcasterSettings
  enabled: true
  messageColor: §f
  messages:
  - Candie broadcaster works.
  - This is default message of CandieBroadcaster
  - You can edit broadcasting messages in config.yml
  offset: 10
  prefix: §4[§bCandieBroadcaster§4]

After running reload command

Code:

# Serhat KAYA

cleaner:
  enabled: true
  messages:
    cleanSucceed: Cleaned successfully
    fiveToClean: The items on the ground will be removed in 10 seconds.
    tenToClean: The items on the ground will be removed in 10 seconds.
  offset: 60
broadcaster:
  enabled: true
  messageColor: §f
  messages:
  - Candie broadcaster works.
  - This is default message of CandieBroadcaster
  - You can edit broadcasting messages in config.yml
  offset: 10
  prefix: §4[§bCandieBroadcaster§4]

I have a class named Config and I'm calling it's load() function on plugin enable.

load method:

Code:

  
        config.options().setHeader(Arrays.asList(new String[] { "Serhat KAYA" }));
        config.addDefault("cleaner", new CleanerSettings(true, 60));
        config.addDefault("broadcaster", new BroadcasterSettings(true, 10));
        getConfig().options().copyDefaults(true);
        save();

        CLEANER_SETTINGS = config.getObject("cleaner", CleanerSettings.class);
        BROADCASTER_SETTINGS = config.getObject("broadcaster", BroadcasterSettings.class);

        BROADCASTER_SETTINGS.messages = config.getStringList("broadcaster.messages");

save method :

Code:

 public static void save() {
        if (config == null || configFile == null) {
            return;
        }

        try {
            config.save(configFile);
        } catch (IOException ex) {
            Log.severe("Could not save config.yml to " + configFile.getAbsolutePath());
        }
    }

To explain it better, BroadcasterSettings class:

Code:

package serhatkaya.candieUtils.types;

import java.util.Arrays;
import java.util.List;

public class BroadcasterSettings extends Feature {
    public String prefix = "§4[§bCandieBroadcaster§4]";
    public String messageColor = "§f";
    public List<String> messages = Arrays.asList(new String[] { "Candie broadcaster works.",
            "This is default message of CandieBroadcaster", "You can edit broadcasting messages in config.yml" });

    public BroadcasterSettings(boolean enabled, int offset) {
        super(enabled, offset);

    }
}

CleanerSettings class

Code:

package serhatkaya.candieUtils.types;

public class CleanerSettings extends Feature {
    public CleanerMessages messages = new CleanerMessages();

    public CleanerSettings(boolean enabled, int offset) {
        super(enabled, offset);
    }
}

CleanerMessages class

Code:

package serhatkaya.candieUtils.types;

public class CleanerMessages {
    public String tenToClean = "The items on the ground will be removed in 10 seconds.";
    public String fiveToClean = "The items on the ground will be removed in 10 seconds.";
    public String cleanSucceed = "Cleaned successfully";
}

Feature class

Code:

package serhatkaya.candieUtils.types;

public class Feature {
    public boolean enabled;
    public int offset;

    public Feature(boolean enabled, int offset) {
        super();
        this.enabled = enabled;
        this.offset = offset;
    }
}

After reloading plugins everything works well, I just need to get rid of that weird class paths (cleaner: !!serhatkaya.candieUtils.types.CleanerSettings)

 

I edited the post. Thank you for reply.
