In JDK-Merlin CardLayout class contains an unapproved changes.
There are two new fields ('vector' and 'currentCard') and an old
field ('tab') has disappeared in the class's Serialized Form.
The removed field was private but it was described in the public document:
Specification of Classes Serialization so it could not be removed
from the class without an approved CCC request.
The same is applicable to the new fields. These changes should go through
CCC as well.
This is a compatibility-related bug.
