<span class="diffaddedchars" style="background-color:#ddfade;">Introduce {{org.hibernate.engine.internal.EntityEntryContext}}, {{org.hibernate.engine.spi.ManagedEntity}}, etc as a means to allow increased performance for Session-related memory and CPU overheads. <br><br>{{org.hibernate.engine.internal.EntityEntryContext}} is a context for maintaining the relation between an entity associated with the Session owning this {{EntityEntryContext}} and that entity's corresponding {{org.hibernate.engine.spi.ManagedEntity}} reference. <br><br>{{org.hibernate.engine.spi.ManagedEntity}} is a contract for describing an entity's association with a Session. It gives us access to information (specific to each entity instance) such as it's {{org.hibernate.engine.spi.EntityEntry}} as well as defining a doubly-linked graph via {{org.hibernate.engine.spi.ManagedEntity#$$_hibernate_getPreviousManagedEntity}} and {{org.hibernate.engine.spi.ManagedEntity#$$_hibernate_getNextManagedEntity}} <br><br>There are 2 forms of {{org.hibernate.engine.spi.ManagedEntity}} supported. First is for the entity to implement the {{ManagedEntity}} interface, either directly or through bytecode manipulation. Second is for Hibernate to "wrap" the entity in a {{ManagedEntity}} implementation (legacy Hibernate did this anyway, in terms of wrapping the entity as it was added to {{IdentityMap}}).<br><br>An Ant task to perform enhancing was added here as well. Gradle and Maven support are tagged in HHH-8306 and HHH-8337, respectively.<br><br>See HHH-7963 for follow-on tasks...<br><br>----<br><br>Initially, this issue started as an investigation into</span>
