IMO, HB/JPA could do a better job of supporting the object identity versus object equality problem.

correlation is related.  but i don't see how this justifies the need for business keys.  it could only show the opposite.  namely that a single business key is not sufficient.  to support correlation in bpel, we would need a set of correlations (set of set of primitive values) for each process instance.
