      Summary

      I'm building an application and encountered in an issue while configuring my POJO class
      Suggestion that inherit 2 more classes, and first one "Entry" contains an ID field of generic type of the class.

       

      org.bson.codecs.configuration.CodecConfigurationException: An exception occurred when encoding using the AutomaticPojoCodec.
Encoding a Suggestion: 'ru.minecomplex.bot.discord.suggest.Suggestion@317cb54d' failed with the following exception:
Failed to encode 'Suggestion'. Encoding '_id' errored with: Can't find a codec for class java.lang.Object.
A custom Codec or PojoCodec may need to be explicitly configured and registered to handle this type.

      My Suggestion.class is:

      public class Suggestion extends Creatable<Integer> {

    private long messageId;
    private String text;

    @BsonCreator
    public Suggestion(@BsonId Integer id) {
        super(id);
    }

}

      My Creatable.class is:

       

      public abstract class Creatable<T> extends Entry<T> {

    protected String owner;
    protected long createdAt = System.currentTimeMillis();

    public Creatable(T id) {
        super(id);
    }

}

      My Entry.class is: 

       

      public abstract class Entry<K> implements Serializable<K> {

    protected K id;

    public Entry(K id) {
        this.id = id;
    }

}

      My Serializable.class is:

      @BsonDiscriminator
public interface Serializable<K> {

    K getId();

}

      Please provide the version of the driver. If applicable, please provide the MongoDB server version and topology (standalone, replica set, or sharded cluster).

      How to Reproduce

      Create a POJO class with double inheritance of classes with generic type containg field of it and try to save it.

      Steps to reproduce. If possible, please include a Short, Self Contained, Correct (Compilable), Example.

      Additional Background

      When I remove the Creatable class inheritance and add it's all fields + id constructor to the Suggestion.class , it solves the problem. So this might give you the all needed information to fix that

      Please provide any additional background information that may be helpful in diagnosing the bug.
