maybe you have to contact the openjpa people what they're doing here. To me
it looks like they shade parts of the JDK into their own library using some
kind of byte code manipulation. However, it seems that this process is not
transparent regarding serialization. Can you try to serialize/deserialize
such a modified Calendar object with Java serialization?
