Manfred Baedke updated COLLECTIONS-900:
---------------------------------------
Description: [https://github.com/apache/commons-collections/pull/628]
changed IteratorChain#addIterator(final Iterator<? extends E> iterator) so that
if the parameter iterator is an IteratorChain itself, the method will add it's

IteratorChain#hasNext() modifies this internal queue, so that #addIterator()
will not work properly anymore. A PR with a test case is linked below. (was:
