[hibernate-issues] [Hibernate-JIRA] Resolved: (HHH-7193) Transaction Rollback not clearing statement batch on Prepared Statement causes issues with statement caching

Transaction Rollback not clearing statement batch on Prepared Statement causes issues with statement caching ------------------------------------------------------------------------------------------------------------ Key: HHH-7193 URL: https://hibernate.onjira.com/browse/HHH-7193 Project: Hibernate ORM Issue Type: Bug Components: core Affects Versions: 4.1.1 Environment: Hibernate 4.1.1 and before Any connection provider that allows statement caching (i.e. C3P0) Reporter: Shawn Clowater Assignee: Steve Ebersole Fix For: 4.1.2 Time Spent: 0.45h The AbstractBatchImpl closes the preparedStatement in a finally block but doesn't call clear in the event of a rollback. This can leave the preparedStatment in a weird state if any type of statement caching is being used. The issue is easily fixed by adding a clearBatch() call to the statement prior to close. I was previously working around this by implementing my own BatchingBatcherFactory in Hib 3 but the API changed forcing me to look at it again. I figured I might as well provide a global fix. I'll add a pull request once I get github sorted.
