[jira] [Created] (MAHOUT-1186) OpenKeyTypeObjectHashMap#clear() has been broken forever.

Jake Mannix created MAHOUT-1186:
-----------------------------------

             Summary: OpenKeyTypeObjectHashMap#clear() has been broken forever.
                 Key: MAHOUT-1186
                 URL: https://issues.apache.org/jira/browse/MAHOUT-1186
             Project: Mahout
          Issue Type: Bug
    Affects Versions: collections-1.0, 0.3
            Reporter: Andy Schlaikjer
            Assignee: Jake Mannix
             Fix For: 0.8


Arrays.clear(array, 0, array.length - 1, FREE);

Means that the last entry in the array is *not* FREE, and hence arrays.clear only *sometimes* empties the array, and hence only *sometimes* clears out all of the entries in the map.  Other times, it leaves one element behind. :(
