      Description

      Good catch! I found what the problem is - there can be only 254 ids
      created within the same millisecond. The test below fails with a
      message "Failed on 254":

      public void testIdPool() throws Exception {
      Set idSet = new HashSet();
      for (int i = 0; i < Integer.MAX_VALUE; i++)

      { assertTrue("Failed on " + i, idSet.add(new ObjectId ("Artist"))); }

      }

      While a slightly modified test succeeds (ok I only waited till 100000
      ids and canceled the test)

      public void testIdPool() throws Exception {
      Set idSet = new HashSet();
      for (int i = 0; i < Integer.MAX_VALUE; i++)

      { Thread.sleep(1); assertTrue("Failed on " + i, idSet.add(new ObjectId ("Artist"))); }

      }
