   Description

   The Hostname class holds a cache for already resolved hosts. This cache reuses
   already resolved InetAddress objects. This cache is useless, because the
   InetAddress class itself has a cached. We should delete this cache.

   Evaluation

   The issue has no visible effects on the code.

   Suggested Fix/Work Around

   Remove the cache from the Hostname class.

   Analysis

   In http://java.sun.com/j2se/1.4.2/docs/api/java/net/InetAddress.html is
   described the caching of InetAddress objects.

   How to test

   A complete TS run is necessary to check that the system is with the fix stable.
   An automatic test is hard to achieve, because the hostname resolving on the
   running host must be changed.


   ATC:  nothing
