      When java heap is large and compressed oops can not be used we still can use compressed klass pointer if Perm Gen size < 4Gb.
      I tried it some time ago but did not finish because it requires a lot of changes, almost duplication of code for compressed oops.
      We can use this bug to implement compressed klass pointers when 6964458 is done.
