org.apache.commons.collections.Bag.removeAll()
(Violation) Remove all elements represented in the given collection, respecting cardinality. That is, if the given collection coll contains n copies of a given object, the bag will have n fewer copies, assuming the bag had at least n copies to begin with.
The {@link Collection#removeAll(Collection)} method specifiesthat cardinality should not be respected; this method should remove all occurrences of every object contained in the given collection. @param coll the collection to remove @return true if this call changed the collection
