[hibernate-issues] [Hibernate-JIRA] Created: (HHH-6598) Immutable entities should not have up-to-date checks performed on a flush

Immutable entities should not have up-to-date checks performed on a flush ------------------------------------------------------------------------- Key: HHH-6598 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-6598 Project: Hibernate Core Issue Type: Bug Components: core Affects Versions: 3.6.7, 4.0.0.CR1, 3.2.5 Reporter: Ian Robertson Attachments: DirtyCheckTest.java When session.flush() is called, hibernate needs to scan all entities currently in session to see which ones are dirty. In some cases, this can become expensive due to the number of entities, especially since every field of each entity must be inspected. Unfortunately, while hibernate will avoid persisting changes made to an entity annotated with @Immutable, it makes the decision to do so only after invoking the getValues() method on DefaultFlushEntityEventListener (even though this method is invoked *after* making the call to requiresDirtyCheck(entity)). I'm attaching a test case which demonstrates this behavior. -- This message is automatically generated by JIRA. For more information on JIRA, see: http://www.atlassian.com/software/jira
