@investr777: Thanks for the detailed report and sorry for the late answer!
The RecordSerializer
currently does not have support for backwards/forwards compatibility. It is a limitation in its design that I realized only after it was originally contributed by Oracle.
See this issue for a more detailed discussion of the problem.
I have created a POC that integrates record serialization back into the default FieldSerializer
and its subclasses. I ran your test-case against this PR and it passes. it will be part of the next major release, Kryo 6.
I'm afraid that for Kryo 5 there is not much we can do to fix this. If you need support for this right now and can't switch to normal classes for cases where you need compatibility, you could write your own record serializer that uses the same logic as CompatibleFieldSerializer
.

@theigl, thank you so much for your reply.
Will Kryo 6 and Kryo 5 have backward compatibility? Will Kryo 6 be able to deserialized data, which were serialized by Kryo 5?

@investr777: Yes, my goal is that Kryo 6 is backwards compatible (See https://github.com/EsotericSoftware/kryo/wiki/Kryo-v6-Ideas).
