Description Andrei Ilitchev CLA 2013-08-06 17:25:17 EDT 
Hit this with ObjectArrayMapping.

AbstractCollectionmapping is not derived from CollectionMapping, therefore
if (mapping.isCollectionMapping()) {
  (CollectionMapping)mapping...

throws ClassCastException.

Note that currently the code relies in several places upon isCollectionMapping method for the mapping having ContainerPolicy.

The correct fix would introduce a new hasContainer method and a careful code examinatio of all calls to isCollectionMapping should follow to find the cases where hasContainer should be called instead.
