Hi Calvin, 1. Enlist I mean that if you want, for example, to get to see what fields present in BinaryObject. In other words, if you want to work with BinaryObject directly. For POJO serialization/deserialization this should not be and issue at all.
2-3. In your case, you have and java.time.Ser in one of the fields of your POJO (or maybe inside of depended object), and it is Externalizable. In such case BinaryMarshalelr falls back to OptimizedMarshaller with all the issues. Try to remove it from your POJOs or make transient.
