Comment 2 Jaroslav Tulach 2011-06-27 07:04:56 UTC

Children.Keys.setKeys(collection) calls Dupl.updateList(collection, ...) and this method uses for (Object o : collection). ConcurrentModificationEx signals that the collection is being modified during this call. It is responsibility of the caller to provide collection which will not be modified during setKeys(...) running.

As all calls arrive from BaseMakeViewChildren, moving there.
