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().
