Convert usage of Hibernate's FastHashMap to ConcurrentHashMap (Java 1.5)
------------------------------------------------------------------------

                 Key: HHH-3050
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3050
             Project: Hibernate3
          Issue Type: Improvement
            Reporter: Gail Badner
            Assignee: Gail Badner
             Fix For: 3.3


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.
