     [ https://issues.apache.org/jira/browse/OPENJPA-2292?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Rick Curtis updated OPENJPA-2292:
---------------------------------

    Description: 
While doing some performance analysis we have found that we can reduce object allocations a number of places in the code base.
* In JDBCStoreManager we can create a simple pool(list) of CancelPreparedStatement/CancelStatement.  
* BrokerImpl.initializeOperatingSet, use a java.util.IdentityHashMap rather than org.apache.commons.collections.map.IdentityMap.IdentityMap.
