CollectionUtils class has a BUG in commons-collections-3.2.1-src.‏

[林蒋]

Hi,
   I have read the common collection 3.2.1 source code, in the
CollectionUtils class, the removeAll method incorrect invoked the
ListUtils.retainAll method, I think the CollectionUtils's removeAll method
should invoke ListUtils.removeAll method. Is this a BUG?

  Best Regards!
