RFR [9] : Add default[Read|Write]Object to java.util.Date

[Chris Hegarty]

Trivial change that came up a few months ago, and again recently, that java.util.Date should call default[Read|Write]Object to strictly conform to the Serialization spec ( even though it does not have any persistent state, which it could conceivably do at some point in the future, but probably won't ).
