3. NullPointerException in SessionImpl.getOrphans()    forum.hibernate.org

We are currently using Hibernate 2.1 with PostgreSQL 7.3.4 and JBoss 3.2.2. I am not including all mapping documents yet since I hope that the problem is clear from the description below.

I get OutofMemoryError when I'm using Hibernate to create 20,000 rows in one transaction. I debuged the Hibernate for a little while. What I got is: SessionImpl doesn't release references to "ScheduledInsertion" objects until the transaction is commited().
