APAR status
Closed as program error.
Error description
In situations where a class contains multiple writeObject or readObject methods in a class hierarchy, the methods of the inherited classes were not being invoked. Only the outer-most child writeObject or readObject methods are invoked. This can result in objects not being properly re-created during deserialization.
Local fix
