Problem seems to be isolated to the Many side of a One-

solution for testing, including a Test case suite

Fixed. JBossCMP was attempting to load the fk into an
object of the type of the current entity's pk instead of
the related entity's pk.
The custom pk code has not been tested well, so keep up the
good work.

I have the same problem with a PK with just an int inside.
