#  The failure occurs when a method is active and

    /*********
Steps to reproduce this problem:
   a. add line breakpoint  in start()
   b. debug
   c. when breakpoint is hit, type continue. You should see output
"Before update..."
   d. change "Before update" to  "After update"
   e. redefine,  and set line breakpoint (see step a)
   f. type continue. You should see output "After update"
   g. change "After update" to "abcde"
   h. redefine, and set line breakpoint (see step a)
   i.  type continue. The output is shown as "After update"

   j. to see "abcde" output,  users will have to pop the stack, and
re-execute method start().
