Even your VehicleDetailsCollection class should implement the Serializable interface.

Implementing Serializable in VehicleDetailsCollectionWrapper class makes only the wrapper serializable and not the VehicleDetailsCollection class.

You need to make VehicleDetailsCollection class also Serializable.

Read Java serialization specs for more:
