Closed as program error.
Error description
When using eXtreme Data Format (XDF) with classes that implement their own readObject and/or writeObject, the super class method can be invoked instead of a subclass implementation of the method that overrides the super class's implementation. This can leave some fields uninitialized which can result in unexpected behavior. An example error that can be seen is a NullPointerException exception when trying to reference fields that were not correctly initialized.
