I agree with you as regards the Swing GUI components -- Sun states that
serialization of these is not dependable between versions, and thus they
are not making any effort to keep steady UIDs.  However, other classes
are actively maintained to be backwards-compatible as regards
serialization (java.util.Calendar is one).  Where classes are expected
to be compatible other major versions of Sun's JDK (say 1.3 and 1.4), we
should aim to be compatible too, IMO, so things like RMI will still
work.  As Japi spots these differences, its not too difficult to track
these things, and fix them as and when there is time (they are really a
major priority, but useful to have nonetheless).  If it is the case that
we shouldn't be handling these, then this should really be noted
somewhere in the on-line material.
