Jakob Braeuchi updated HHH-5275:
--------------------------------
Attachment: My_Oracle10Dialect.java
dialect with improved lockhandling
> Criteria.setLockMode does not work correctly
> --------------------------------------------
>
> Key: HHH-5275
> URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5275
> Project: Hibernate Core
> Issue Type: Bug
> Components: core
> Affects Versions: 3.5.2, 3.5.3
> Environment: Hibernate 3.5.2, Oracle 10 (using org.hibernate.dialect.Oracle10gDialect
> Reporter: Björn Moritz
> Priority: Minor
> Fix For: 3.6.1
>
> Attachments: My_Oracle10Dialect.java, My_Oracle10Dialect.java, TestCase.zip
>
>
> The LockMode set via Criteria.setLockMode does not generate a ' for update' SQL statement. In the org.hibernate.dialect.Dialect class only the LockOptions are used for determining a possible addition to the SQL statement if using pessimistic locking. This behaviour is different from Hibernate 3.1.3.
> In the supplied TestCase two threads are reading the same database record; one of those threads should use pessimistic locking thereby blocking the other thread. But both threads can read the database record causing the test to fail.
