    Description

      1) Constructor cache leaks classes and their attendant static overhead forever.
      2) Class cache inside conf used when getting JobConfigurable classes has an epic lock.

      Both bugs are files in Hadoop but will hardly ever be fixed at this rate. This version avoids both problems
