FieldsOfSimpleClass now passes. JPOX latest now supports serialised PC fields 
and serialised Interface fields.

The only thing stopping FieldsOfSimpleInterface passing is probably that JPOX 
doesn't support embedded interface fields. I don't consider this a mandatory 
part of JDO2. Embedded interface fields are basically the same as embedded PC 
fields where the embedded PC field can have inheritance. That is, with 
embedded interface fields you can have different objects being embedded 
(different interface implementations) and hence different columns can be 
needed in the table. The same is true with embedded PC fields where the PC 
object has inheritance, and so different columns needed dependent on the 
object being embedded. Since the current JDO2 spec doesn't support having 
discriminators as part of the <embedded> block then the JDO impl has no way 
of distinguishing the type of the object that has been embedded.
