Description Vikram Bhatia CLA 2012-02-01 02:00:29 EST 
There is a possibility of a deadlock while merging a collection into the shared cache and IndirectList when Vector is used.
Comment 1 Vikram Bhatia CLA 2012-02-01 02:07:51 EST 
ContainerPolicy.mergeChanges() currently synchronize on target value or its delegate if instance of an IndirectCollection while merging the changes from the change set, i.e, removing and adding objects to the collection from the change set. This can cause a possible deadlock scenario while using native ORM if Vector is being used for the collection.
