                 Key: COLLECTIONS-722
                 URL: https://issues.apache.org/jira/browse/COLLECTIONS-722
             Project: Commons Collections
          Issue Type: Bug
    Affects Versions: 4.1
            Reporter: E P
         Attachments: IteratorUtilsTest.java

IteratorUtils.chainedIterator() performance degrades when chaining iterators 
with chained iterators.   The slowdown appears to be exponential, based upon 
the number of chains created.  The attached test shows the issue.
