| 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(). |
