      The Bug Id 4503092 fails in Hopper (build 1.4.1-auto-tl-128b) on
      win2k, NT,XP.

      The LotsOfChannels.java is attached, this test case is written by you.

      We have added
       System.out.println("pass 1111");
       after the first loop
        and
        after the second loop
        System.out.println("pass 2222");
         
        But it prints only the first one.
