including a unit test. the key is just to make the number of times in the for loop greater than datanucleus.connectionPool.maxActive.

this unit test will fail because the connection is never closed. the connection should be closed when the pm is closed.

Thx for the report. Provided fix would go off and allocate a connection if not yet allocated hence hitting performance at close. Better way was just to use the existing listener mechanism for when an ObjectManager is closing and let the ConnectionManager clean that ObjectManager's information out.
