Quoting Craig L Russell <Craig.Russell@Sun.COM>:

Remember the history about List.contains? Add, contains and many other
operations requires "(o==null ? e==null : o.equals(e))", in that sense you have
to load all objects.

JPOX, FYI, does not follow this rule and runs equality by comparing the identity
columns of these objects (primary keys for FCO) or the values for embedded
fields.
