Many of the MetaData persistence delegates are invalid because the private state of the these components have changed due to the refactoring as a result of 4864304.

For example, the javax_swing_JComponent_PersistenceDelegate will throw an exception since JComponent no longer contains the private fields minumumSize, preferredSize, maximumSize.

Should reexamine all invocations of MetaData.getPrivateField to see if the fields are still valid.
