Juergen Hoeller opened SPR-14487 and commented
SerializableTypeWrapper restores type accessor methods on deserialization. It does so against the concrete type implementation at this point which breaks on JDK 9 due to an enforced visibility barrier. Resolving the method against the declaring interface is more appropriate in any case and also solves the JDK 9 issue.
Affects: 4.3.1
