[hibernate-issues] [Hibernate-JIRA] Updated: (HHH-6862) Reuse cached entryArray of IdentityMap in StatefulPersistenceContext as much as possible

Reuse cached entryArray of IdentityMap in StatefulPersistenceContext as much as possible ---------------------------------------------------------------------------------------- Key: HHH-6862 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-6862 Project: Hibernate Core Issue Type: Improvement Reporter: Sanne Grinovero Assignee: Sanne Grinovero Priority: Minor Fix For: 4.0.0.next Attachments: OGM-Map-4 - before HHH-6862.png, OGM-Map-5 - after HHH-6862.png There are different options to iterate the containers of a StatefulPersistenceContext, and these iteration operations happen frequently. Usage of IdentityMap is able to cache cache the array it creates to provide a safe iteration during modifications, so I've collapsed all usage of the PersistenceContext to use less different iteration approaches, and this resulted in a small performance improvement and some code simplification.
