Jeremy Bauer commented on OPENJPA-1248:
---------------------------------------
I committed a partial fix for Oracle under revision 834564. With the exception
of adding the ConnectionRetainMode setting to the test config, the tests pass
as-is (ie. expected behavior is unchanged). I also doc'd the
ConnectionRetainMode requirement in the Oracle section of the manual.
One potential issue may still remain. If a LOB column contains a null (ex.
inserted by an external application) and OpenJPA tries to update that value a
failure may still result. The cumbersome patch I submitted for OpenJPA-1249
will handle that case, but I have a more direct approach in mind that uses SQL
instead of native APIs.
