Release note applies to both this issue and to JDK-4802647

Release note text: In prior releases some implementations of Collection.removeAll(Collection) and retainAll(Collection) would silently ignore a null parameter if the collection itself was empty. In this release collections will consistently throw a NullPointerException if null is provided as a parameter.
