Bug on flushing context with modified non initialized lazy collection ( It works fine on hibernate 3.5.6 ) ---------------------------------------------------------------------------------------------------------- Key: HHH-7247 URL: https://hibernate.onjira.com/browse/HHH-7247 Project: Hibernate ORM Issue Type: Bug Components: core Affects Versions: 3.3.2 Environment: This problem occurs on hibernate 3.3.2 and 3.3.1 ( The latest JPA1 hibernate implementations I've found ) Reporter: Hood Wilson Gusso Silva Attachments: hibernateTc1.zip This is a quite trick problem that only occurs on modified lazy collections that aren't initialized ( Like when you do a add() operation without any previous size() or get() or toString() ... ) I think that it will be easier to show it by a commented source. I made a little database (with only 3 simple tables to make possible to reproduce the error.) + a maven project The maven project have 2 file called pom33.xml and pom35.xml so it's possible to easily see how the error occurs on 3.3.2 but not on 3.5.6 the script to recreate the problem is available within the project too. BTW the source do a rollback ( So it won't change the database ). If you want changes on db it will be necessary to change the rollback() to commit() -- This message is automatically generated by JIRA.
