Thanks for the quick reply, gloeglm.

The root cause in the stack trace is:

Caused by: java.sql.BatchUpdateException: Invalid argument value: Duplicate entry '2' for key 1

If this does not fix it, please show more of your mapping, eg. the class and id parts of it, too.

Hm, this looks fine to me so far ... what SQL is generated, and what constraint is violated? Enable logging and check the log.
