Hibernate version: 3.1.2

Background:
I have a bidirectional, non-lazy one-to-many association between two domain objects. We use Oracle10g database and have implemented optimistic locking using ORA_ROWSCN meta-column as version column in Hibernate. A bug in Oracle makes ORA_ROWSCN not to work in outer join queries.

Problem:
When fetching the object that has a set of another objects using everything goes well (the fetching is done without outer join in SQL level, two different queries gets executed). But when calling the refresh query contains outer join for some reason I cannot understand (only one query gets executed).

I have tried to disable the outer join by putting different combinations of fetch="select" and outer-join="false" attributes in both ends of the association, but that seems not to help.

Question:
How can I disable outer join from the refresh query?

I'm digging the forum, but I got exactly the same problem and the solution, so if it can help people:

Add
hibernate.max_fetch_depth=0
in hibernate.properties file.

(this solution expect that you never really want to use outer join in mapping)
