session.lock() with UPGRADE_NOWAIT no longer works with Oracle9 --------------------------------------------------------------- Key: HHH-1027 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-1027 Project: Hibernate Core Issue Type: Bug Components: core Affects Versions: 3.1 rc 1 Environment: Hibernate 3.1 beta 3 Oracle 9 Reporter: Achim Lörke Assignee: Steve Ebersole Priority: Blocker With fix HHH-924 the SQLStateConverter replaced the version from Oracle9Dialect. This generic converter doesn't handle the error codes from Oracle when UGRADE_NOWAIT is used and the row is already locked, so instead of getting a LockAcquisitionException a GenericSQLException is thrown. (org.hibernate.exception.ErrorCodeConverter which handled this kind of SQL errors was removed, too). This breaks a lot of code which relies on locking with Oracle.
