[classlib][pack200]CPUTF8.hashCode() is slow
--------------------------------------------

                 Key: HARMONY-5907
                 URL: https://issues.apache.org/jira/browse/HARMONY-5907
             Project: Harmony
          Issue Type: Improvement
    Affects Versions: 5.0M6
         Environment: Latest pack200
            Reporter: Andrew Cornwall


The unpack process spends a lot of time doing CPUTF8.hashCode() - which does String.hashCode().
We can save about 1.5 seconds of my 39 second test case (about 4%) by caching the hashCode.
(I thought we did this before - or maybe I dreamt it?)
