Andy Jefferson commented on JDO-509:
------------------------------------
All of this is caused by the change in the model. The fact is that you now are
trying to embed an interface type that is not persistent (neither
PersistenceCapable, nor "persistent-interface"). Ok, you are specifying
"field-type" but sadly JPOX doesn't cater for that (my previous fix was a guess
since I didn't write support for PI's and turns out that it only worked around
metadata consistency issues). JPOX's handling of "persistent-interface" is for
use of relation fields that are either PC or persistent-interface only.

> Imagine that the existing interface company.ICompany is not persistent and
> there is a new interface company.PICompany that extends ICompany. Existing
> xml metadata is modified to refer to PICompany rather than ICompany. On
> enhancement, we get the error below. Craig suggests that using the
> reflective "getDeclaredMethod" instead of the reflective "getMethod" could
> give this error. These are changes that we would like to check in for the 2.1
> maintenance release.
