Improve the scalability of PreparedQueryCacheImpl
-------------------------------------------------

                 Key: OPENJPA-1723
                 URL: https://issues.apache.org/jira/browse/OPENJPA-1723
             Project: OpenJPA
          Issue Type: Improvement
    Affects Versions: 2.0.0, 2.1.0
            Reporter: Rick Curtis
            Assignee: Rick Curtis


On a large multicore machine (24+cores) there is a large amount of contention in the PreparedQueryCacheImpl
lock. 

In this JIRA I'm going to utilize the j.u.c.ReentrantReadWriteLock to improve read/write throughput.
