How to serialize Throwable?

[Adorjann]

Hi, I would like to serialize an object that contains a field of type Throwable.

class ObjectToSerialize{
    Throwable throwable;
}
public class Main {

    public static void main(String[] args) {

        ObjectToSerialize objectToSerialize = new ObjectToSerialize();

        final SerializerFoundation<?> foundation = SerializerFoundation.New()
                .registerEntityTypes(ObjectToSerialize.class);
        final Serializer<byte[]> serializer = TypedSerializer.Bytes(foundation);      //line 18
        byte[] data = serializer.serialize(objectToSerialize);

        ObjectToSerialize restored = serializer.deserialize(data);

    }
} 

The code above produces:

Exception in thread "main" one.microstream.persistence.exceptions.PersistenceExceptionTypeNotPersistable: Type not persistable: "class java.lang.Throwable".

If you can please point me to documentation or an example explaining how to do this.
Many Thanks!

Serializing Throwable and derived types is currently not supported. Instead of using that type you may use the stack trace and message for serialization.

Thanks for your answer!

Interesting that Throwable and derived types are not supported.
Because on this page it is claimed, that there are no limitations and any object can be serialized. How does that fit together?

For "RPC-like" mechanisms serializing exception instances would be useful (if not essential).
