Question

I am removing Hibernate for a certain portion of our larger application where we have been seeing database contention and deadlocks that could never be isolated or recreated consistently.

Parent-child relationship, where the children are mapped in our .hbm.xml as a Set: Hibernate uses their own implementation of Set (specifically PersistentSet).

We do correctly/properly program against the java.util.Set interface in referencing a parent’s children.

My question: Now that I need to pull out Hibernate, which implementation of java.util.Set is the most comparable (or best replacement in a non-Hibernate world) for Hibernate’s PersistentSet?

Answer 1

Figured it out.

Hibernate’s PersistentSet uses java.util.HashSet under the covers. Thus, that would be the best replacement for PersistentSet when removing Hibernate.
