Andy Jefferson commented on JDO-517:
------------------------------------
Why are classes annotated with @NotPersistent on fields and @Persistent on
properties ? I would expect (from other persistence specifications) to have one
or the other annotated. Annotating fields (with any annotation) implies that
fields are used for persistence, yet then it encounters properties with more
annotations.
Does the spec define the equivalent of access-type in JPA ? and what is
supposed to happen when the user takes leave of senses and annotates everything
under the sun ?
