Gary Gregory commented on COLLECTIONS-665:
------------------------------------------
Have you tried using a {{org.apache.commons.collections4.iterators.FilterIterator<E>}} with a {{org.apache.commons.collections4.functors.NotNullPredicate.notNullPredicate()}} like:
{code:java}
Iterator nonNullIterator = FilterIterator.FilterIterator(myCollection.iterator(), NotNullPredicate.notNullPredicate());
{code}
