----------------------------------------------------

                 Key: COLLECTIONS-298
                 URL: https://issues.apache.org/jira/browse/COLLECTIONS-298
             Project: Commons Collections
          Issue Type: Wish
          Components: Collection
    Affects Versions: 3.2
            Reporter: Benjamin Bentmann
            Priority: Minor


The API would look inconsistent if
- CollectionUtils.isEmpty(null) == true
- CollectionUtils.size(null) == 0
but
- CollectionUtils.sizeIsEmpty(null) throws IAE
