Hello everybody!
I have the next application configuration: Karaf 2.3.1; Hibernate jpa-2.0 1.0.1.Final; Hibernate - 4.2.7.Final; Postgress 9.2.

I have one proven case when changes in DB will not remove after transaction is roll-backed.

Case is very specific and rollback works fine for all other cases in this environment.
Problematic case is:
- Mapped entities: A has B as child. B has C as child;
- New entity A and it’s new child B and it’s new child C prepared;
- New entity persisted by one getEntityManager().persist(A) command. During this actin 3 related tables are populated.
- After this DB operation but within scope of the same container managed transaction code throws exception.
- Newly 3 created records are in DB. But it is wrong!

According the log transaction was roll-backed


Any ideas or suggestions are welcome.
Thanks in advance.

A small but important clarification.

I have clear evidence that our project, environment and transaction configuration is correct. When entity A without children persisted, transaction and rollback working absolutely fine.

So we have only one specific case when rollback doesn't work.
In log I could see tha same set of messages for seccessful and failed rollback cases. And according the messages rollback was performed.
