Knut Anders Hatlen updated DERBY-3650:
--------------------------------------

         Component/s: Store
                      SQL
    Issue & fix info: [Known fix, Repro attached]
            Assignee:     (was: Mike Matrigali)

Triaged for 10.5.2.

- Checked "Repro attached"

- Checked "Known fix" since a (not commit-ready) patch proposal is attached

- Added components SQL and Store since they are touched by the suggested fix

- Marked as unassigned since there has been no activity in over a year

- Left the Regression flag on since the network client problems were not seen in earlier versions.
The underlying embedded issue can be seen all the way back to 10.0.2.1

> Derby + Hibernate JPA 3.2.1 problem on entity with Blob/Clob
> Hi,
> I'm using Derby in Client - Server mode with Hibernate JPA EJB 3.0.
> When a query on an entity containing a Clob and some joins on other entites is executed,
an exception with the following message is thrown:
>   XJ073: The data in this BLOB or CLOB is no longer available.  The BLOB/CLOB's transaction
may be committed, or its connection is closed.
> This problem occurs when the property "hibernate.max_fetch_depth" is greater than 0.
> When hibernate.max_fetch_depth=0, the query works.
> If Derby is configured in embedded mode, the query works independently of the value of
hibernate.max_fetch_depth.
> On the Hibernate's documentation, the advised value of hibernate.max_fetch_depth is 3.
> Could you explain me if I made something wrong ?
> Thank you.
> Stephane
