Could not find matching type descriptor for requested Java class [...]; using fallback

Description

Types that are persisted using JPA Attribute Converters (@Convert(converter = SomeClassConverter.class)) that do not implement Serializable cause warnings during the application startup:

The application is working fine nonetheless and the warning goes away if I make the type implement Serializable.

I've looked through the documentation, the issue database and the source code and I'm not sure whether this warning is a reason for concern. If it is, I would appreciate if the warning could be more helpful, e.g. by telling me what to do about it. Otherwise the warning should be demoted to a less alarming log level.
