If you look at the exception that is thrown from the database, it's a

This might have been caused by a unique constraint, which would not
be properly reported as EntityExistsException.

Sadly, there is no standard SQL exception that specifically tells the
provider (OpenJPA) that there was a primary key constraint violation.
And you might also note that every database has its own way to report
exceptions like this.

What the EntityExistsException does is to report that there is
already an entity with the same primary key in the persistence
context. It doesn't report that there was a problem writing the
entity to the database.


If you're keen on "fixing" this situation, I'd encourage you to
volunteer to look at the databases and how they report unique and
primary key constraint violations and see if it's possible to parse
the sql code and report string to positively identify a primary key
constraint violation.

an pluggable exception factory (in open-jpa) might make this approach
a little easier
