TTY: redefine class clears breakpoints but clear still lists breakpoints

      Description


      In the JVMDI spec RedefineClasses is specified to clear all breakpoints
      in the class. However after redefining a class, jdb's 'clear' command
      reports breakpoints that it previously recorded. This is confusing
      for developers. I attached test case which I need to put into the regssionsInWaiting area.

      Fixing this issue completely probably requies that jdb become class
      loader aware (4519542) so as to ensure that the correct breakpoints are
      removed from the jdb environment.
