OpenBooks should used container managed persistence when deployed in an application server.
-------------------------------------------------------------------------------------------

                 Key: OPENJPA-1824
                 URL: https://issues.apache.org/jira/browse/OPENJPA-1824
             Project: OpenJPA
          Issue Type: Bug
          Components: samples
    Affects Versions: 2.0.1
         Environment: Windows Sever 2003
            Reporter: Rohit Dilip Kelapure
            Priority: Minor


OpenBooks is using an app managed persistence context and it isn't cleaning up properly. openbook.server.ServiceFactory.getService(...)
creates an EMF, but it is never closed.
OpenBooks application is using an app managed persistence context which is NOT cleaned up
correctly when deployed in a JEE server.
This results in the JEE container JPA Runtime does NOT calling DataCacheManager.close() on
the DataCacheManager plugin.

The container JPA Runtime does NOT call openjpa.DataCacheManager.close() when the application
is stopped.
This does not give a chance to any OpenJPA L2 cache provider to cleanup their resources and
remove cache instances from static hashmaps. utlimately resulting in a memory leak.
