Hi Hongjin,
We encountered a similar problem in another scenario, the only
difference being that in our case, after merge, OpenJPA incorrectly
concludes that a preexisting entity is new, at the time of commit, and
errors out early. So instead of the PersistenceException you got, we
get an ObjectExistsException. But the cause seems to be the same.
We're looking into it.
Thanks for the analysis - it definitely helps.
