Comment 9 for bug 744035

As of revision 326 i have reason enough to believe that the current implementation of Key Value Pairs works

Ive tested the putting and getting of a Serializable custom class KVPtester in the datastore.
The output text for testing the KeyValuePair storage can be seen in stdout when the Populate Datastore button is pressed

This however is put and gotten from the server side implementation. Im not sure if the Class will survive transportation across the GWT RPC layer if transported from the client side, but it is my understanding that any object marked Serializable/IsSerializable will - and that our problem was the actual storage of the serializable class in the KVP itself
