> The performance test attached to HHH-2645 shows that java.util.concurrent.ConcurrentHashMap (introduced in Java 1.5) performs nearly as well as org.hibernate.util.FastHashMap. Hibernate needs to move to Java 1.5 before this can be done.
> As noted in HHH-2645, it might be worthwhile to convert usages of FastHashMap to ConcurrentHashMap so that FastHashMap does not need to be maintained.
