In this commit the bottom change slipped in and should have been part of 
r1797161 but anyway it's quite simple and clear

Log:
Improved: EntityListIterator closed but not in case of exception
(OFBIZ-9385)

This is an improvement only because no cases were reported. But obviously in
case of unlucky exception after the EntityListIterator creation and before it's
closed the EntityListIterator remains in memory.
It should be closed in EntityListIterator.finalize() but the less happens there
the better.

The solution is to use try-with-ressources
