Hi,
After upgrade from EclipseLink M3 to M6 we
a problem with OneToOne relationships using interfaces and target entity. I
have created a small dummy example which causes the error (at deploy time) and
attached the corresponding error trace. Please let
me know if you need me to provide more
information.
Hope someone are able to tell me what is
wrong or if a workaround exists.
Best regards,
Rune
