Rick Curtis closed OPENJPA-2249.
--------------------------------

       Resolution: Invalid
    Fix Version/s:     (was: 2.3.0)
         Assignee: Rick Curtis

After further research, my solution proved to shift the costs rather than remove them. Closing
this issue as invalid.

> I have found that when detaching the entire persistence context we create a new collection
of all items that need to be detached but we could be smarter and just create an intelligent
iterator. This new iterator will iterate over each collection/map that needs to be detached.
> In local perf testing this showed a marginal improvement.
