<p style="margin: 10px 0 0; margin-top: 0">StatefulPersistenceContext. getEntry( Object entity) returns the EntityEntry that has been cached in the enhanced ManagedEntity, so we need to check that the cached EntityEntry has been added by the current PersistenceContext or a different PersistenceContext.</p>

<p style="margin: 10px 0 0; margin-top: 0">Would it be better represented by a Map , so ManagedEntity.$$_hibernate_getEntityEntry(PersistenceContext persistenceContext) would return the correct EntityEntry object. This would be an API change though, so not backward compatible.</p>
</blockquote> <p style="margin: 10px 0 0">But this is exactly what we had before - a Map based solution. Except before at least that was limited to one Map per Session/PersistenceContext. Here, what you suggest, would require a Map per entity instance. Ugh. I can't see how that performs anything but worse than what we used to have.</p> <p style="margin: 10px 0 0">The bottom line is that we need some form of mapping to describe "here is the persistence state (status, etc) for a given entity in association with this given Session/PersistenceContext". And we really do not have that today. What we have today since implementing the perf team's recommendation is "here is the persistence state (status, etc) for a given entity" - the entire piece about "in association with this given Session/PersistenceContext" is missing. </p> <p style="margin: 10px 0 0">I get that maintaining this Map on the entity (ManagedEntity) will "work". I think the question really is about performance oddly enough <img class="emoticon" src="cid:jira-generated-image-static-smile-0deb5d75-1492-441e-a1a5-41a5a70a6275" height="16" width="16" align="absmiddle" alt="" border="0"></p> </td>
